The Ruins (2008)
What the critics said: "Comes off essentially as routine, conceptually silly horror content," Dennis Harvey, Variety; "Lumpish, static, and obvious," Owen Gleiberman, Entertainment Weekly; "Back in the day, Richard Pryor might have mined a comedy routine from this movie," Matt Zoller Seitz, New York Times.
Why it's actually good: Yes, The Ruins, Scott B. Smith's adaptation of his own novel, is gory and simplistic, but that's part of the lost-in-the-jungle story's charms. Not only does the viewer wait (in painful suspense) for the next piece of graphic violence to hit the screen, but the setting also provides a powerfully and ironically effective sense of claustrophobia. Killer plants may be a bit too silly to work as a reliable horror villain (blame Little Shop of Horrors) but director Carter Smith pulls it off quite well in this icky, sticky, visually distressing piece of horror mayhem.
