What horror movie are we today?

Today, we're The Ruins.

The latest issue of Science News magazine kicks off a new story about plant intelligence with some imagery right out of a horror flick:

In a somewhat different world, Consuelo M. De Moraes would be revolutionizing vampire fiction.

Her lab at Penn State University studies predators that entangle prey in a tight embrace, pierce victims’ tissue and suck out nourishment. In the last few years, De Moraes and her colleagues have found that the predators even hunt down prey by scent.

Creepy as her predator, Cuscuta pentagona, is, it is also, frankly, a plant. Better known as five-angled dodder, its orange tentacles bypass the porcelain throats of young women in favor of the slim stems of young tomato plants. De Moraes and other researchers are showing that plants behave and misbehave as dramatically as animals. But there’s still not much hope for a feature-length dodder movie.

“I think most people regard plants as being pretty unresponsive and stuck in one place,” laments ecologist Richard Karban of the University of California, Davis. “Now, animals, they’re interestingbecause they can change and act in response to their environment.”

It’s a dichotomy Karban doesn’t accept for one second. When he and an animal behaviorist recently supervised a grad student, he remembers, “I would constantly want to say, ‘Oh yeah! Yeah! Plants do that too!’” Recent findings on plant capacities, he declares in a 2008 paper in Ecology Letters, reveal “high levels of sophistication previously thought to be within the sole domain of animal behavior.”

Even plants less vampirish than Cuscuta vines forage strategically for their food, and there’s evidence that plants fight each other over resources. In a broad sense of the word, plants communicate — some essentially scream for help. Also, a plant can respond to stimuli depending on its history of previous experiences, a tendency Karban is willing to call a sign of memory.

Movies: Hollywood and vine.

Not entirely unlike the remains the vegetal baddie of The Ruins leaves behind, the film version of Scott Smith's sophomore novel is stripped to the bare bones. Compressing Scott Smith's 300+ page book into in a nimble 91 minutes, director Carter Smith (no relation) pares the novel down to its most basic moving parts. The results are mostly postitive. The film takes the often dreadful, dwindling feeling of the novel and tightens it into a more muscular and propulsive tension. This is, I think, a good move: the screen usually demands tighter storytelling. The cost, however, comes at the characterizations of our protagonists, whose personalities and conflicts are flattened for the sake of dramatic efficiency.

The plot, for those familiar with novel, remains pretty much the same. Four young Americans partaking are busy drinking, dancing, sunning, and puking their way through a Mexican resort vacation. There's Jeff, the Responsible One, who horror fans might recognize as one of the teens/meat sources from the Texas Chainsaw Massacre remake. Jeff's dating the boozy and flirty Amy, who played Donnie's love interest in Donnie Darko. They're traveling with ex-X-man Iceman, here known as Eric, and his Stacey, who appeared as herself in, of all things, The Real Cancun, the MTV produced Spring Break trash-umentary that would have been greatly improved by the presence of a man-eating plant. These four victims to be fall in with a German tourist and a trio of wacky Greeks. The German is named Mathias while the Greeks are totally unintelligible and remain unnamed, but this hardly matters as the Greeks' chief interests seem to be drinking heroically, wildly flailing about in a wacky manner, and shouting "Whoooooooo!" a lot.

For their last day, the named protagonists and one of the Greeks (it doesn't matter which) decide to trek into the jungle to check out an archeological dig that Mathais' brother is supposedly working. On arriving at the ruins, a single stair step pyramid covered in vines, the tourists are quickly surrounded by locals armed with bows and firearms. These locals are determined to keep our hapless hikers at the site. They're so determined, in fact, that they kill the nameless Greek when he attempts to approach one of them. Trapped on top of the pyramid, our soon-to-be-fertilizer learns the grim secret of the ruins. The decaying structure is home to a sinister meat-eating plant species. From this point, things go from "downhill" to "shear cliff-face" and we watch as the heroes have what must surely rate as one of the single worst vacation experiences of all time.

There are a few key differences in the plot: the character list gets whittled down faster, the vine is somewhat "depowered" (no acidic sap and its powers of sonic mimicry are scaled back a bit), the story unfolds over the course of fewer days, some of the escape attempts that appear in the book are dropped entirely, and, perhaps most importantly, the film has a very different ending. The tone is shifted too. In the book, personality clashes between the four main protagonists - five really, Mathias is more important in the novel - are crucial to the story. In the movie, these get reduced to a couple off dramatic screaming matches that come and go without really impacting the film's direction. This is for the best. The characterization and tangents Smith could use to build his cast of characters would have bogged the movie down. Instead of being a strange parable of the failure of people to work together (shades of Smith's first novel, A Simple Plan), the film becomes a pretty straightforward struggle for survival.

Like the book, the tension the film builds is not one of sudden "jump-out" scares (though there are a couple of those). Instead, the film's suspense comes from a steady ratcheting up of the hopelessness of our protagonists' situation. This is less about thrills than a steady sinking feeling. This doesn't mean the flick isn't without its gory moments. Two surgical scenes, one well-meaning but conducted under nearly Neolithic conditions and the other more crazy and self-inflicted, stand out at the high or low points in this, depending on your point of view. The plant looks good – the combo of puppets and CGI go a long way to making the most outrageous aspect of the flick believable enough to be enjoyed without feeling stupid. The acting on the part of our four main characters is solid. Because this is almost a stage piece, with a majority of the action taking place on a tiny little chunk of the pyramid's roof, the actors all had to carry a considerable portion of the film. All of them did a good job.

The Ruins is a smart, effective, and mostly entertaining adaptation of a deceptively simple novel. Less a dumbed-down version of the original than a distilled version, the film is an original standout creature feature in a year that looks like it will otherwise be dominated by limp, half-hearted slasher remakes and retreads.

Now, just so you get the full story, here's a really hilarious review that thought the movie really sucked – and it acts the film out with figurines in the blogger's garden (sort of garden, I guess – she lives on a Christmas tree farm, no foolin' – perahaps her blatantly pro-vegetation lifestyle is at the root, so to speak, of her The Ruins hate, but that's just unfounded speculation on my part). It's darned funny, but the reenactment does give away the end, so you've been officially spoiler notified. Don't bring your bitchin' and moanin' to me, 'cause I won't give a hoot.

Book: The demon weed with roots in hell!

Critical reaction of Scott Smith's second book, The Ruins just released in mass-market paperback, was decidedly mixed. This is, on reflection, unsurprising. His debut effort, the blockbuster A Simple Plan, was one of those crossover genre hits that manages not only to deliver the goods, but touch a deep and resonant nerve. Mining the same ground as its spiritual predecessor, the genre-crossover classic The Treasure of the Sierra Madres, the plot was brilliantly straight forward. A group of three men find a bundle of cash. To keep it, all they have to do is keep their mouths shut and trust one another. Of course, everything goes to utter hell and what could be an exercise in suspense nastiness turns into a brutal portrait of human souls turned monstrous by greed.

In contrast, The Ruins features a super-intelligent man-eating plant.

Seriously. Like a more vicious, splatter-punk version of Audrey II.

You can see how many critics, especially those who had perhaps felt that they were already dangerously close to slumming it when they read Smith's first novel, turned up their noses. After all, is their any creature feature cliché cheesier than the man-eating plant? Images of shambling men in rubber tree-suits spring to mind; maybe you imagine foam "vines" swung about wildly on visible wires.

Well, the disdainful critics were full of poop. Smith's novel takes the hokey B-movie concept and strips it clean of every last vestige of Navy Versus the Night Monsters camp. Using a finely drawn cast of characters and placing them in a plot that is as eerie and surreally inevitable as the snap motion of a Venus flytrap, Smith builds a novel that, despite its bulky 500-page length, is taught and merciless. The Ruins worthily fulfills on the promise of Smith's exceptional debut.

The novel follows the story of four young American tourists (the tourist is the new small-town teen of the horror world) on an off-season vacation in Mexico. There they run across a friendly German tourist, on vacation with his brother, and a trio of rambunctious Greeks who, despite not speaking a word of English, glom on to our protagonists. The German informs them that his brother has gone to an archeological dig in the jungle inland, chasing after a hottie archeologist he met earlier. The group decides that a hike through the jungle might be fun and the four Americans and one of the Greeks take off to make a day of it. To the readers great un-surprise, things go terribly wrong. Shortly after finding the abandoned site, our heroes get trapped there by the locals who seemed determined – lethally so – to keep them at the site of the dig. Trapped without supplies, our heroes' problems get horrifically worse when they find that, sharing the dig site with them, is a system of seemingly sentient vines that live off the fluids and flesh of human beings.

The plot actually shares a sort of conceptual similarity with A Simple Plan. In both cases, our protagonists are stuck in situation that slowly, relentlessly spirals out of control. Though there is plenty of gore and high-res gross out materials (Smith is downright Rabelaisian in his eagerness to depict various bodily fluids), the real violence of Smith's book comes from his own unyielding narrative brutality. Like all good horror authors, Smith is merciless when it comes to putting the screws to his own creations. What makes him a great horror author is that he never loses sight or sympathy for the humanity of his characters. They remain fully realized characters throughout the ordeal. This at once makes the story more involving and more repellant. If our protagonists were the pasteboard cutouts of most low-grade genre fiction, we wouldn't care about them and the slow green deathtrap they find themselves in would be more tedious than frightening. On the other hand, getting to know these characters makes their fates all the more distressing, especially as the bodies begin to pile up.

Thinking back on it now, sympathy is the wrong word. Smith is something like an anatomist of genre fiction personality. His characters are "full realized," but not in the sense that they remind us of people we know. Instead, they are meticulously constructed extensions of genre types – as if he intended to make the trappings of genre fiction real rather than bring a level of the real into the context of genre fiction. This fits with the rest of Smith's MO: just slowly and steadily push everything to its most extreme conclusion.

Smith's A Simple Plan was such a great debut novel that any follow up was bound to receive a mixed reaction. The Ruins not only holds up on its own; Smith should be given credit for taking his brand of relentless psychological suspense and reworking it into a gutsy, gory concept that doesn't feel like retread of modern horror plots or his own instant classic first book.

You can find The Ruins anywhere they sell readables and the new paperback edition will only set you back about 8 smackers.
