Ok, the first 45min or so of the movie is wack ass and probably might even fall asleep, but when they get into the cave shit starts to pick up, this movie is extremely grussom (not sure if thats spelled right), probably one of the few horror movies that actually made it this year, plus its rated R so none of that bullshit you see in pg-13 movies. Fucked up part was we ate right before we watched the movie and damn that shit made my stomach turn. Overall its worth the watch.
