i watched this last night, and i don't care what anyone says, the idea behind it is genius. there is not one other film (that springs to mind) like it. a brilliant take on the horror genre. a necessary must when watching the film is suspending disbelief, putting yourself in their position, imagining you're out in the woods, lost for days and fucked up shit is happening. whatever, I was spooked. great film. I got chills.
