It was a much better film than 'Cabin Fever', and a bit better than I was expecting. It takes quite awhile to get started, but they do a good job setting up the plot--although there is a sex-overload in the first third of the film, which is a stark contrast to the rest of the film. I can't remember one scene in the first third that didn't have sex or nudity.
Eli Roth does a good job of creating a tense movie, but he likes to create tense moments that lasted too long--which makes the movie somewhat frustrating... It's not much of a gore-fest, but it is graphic. My friends who saw it with me forgot that it was low-budget horror film by today's standards. The imagery created was indeed disturbing, it's no Mikai film (granted he does a great job replicating his sense of humor), but good none-the-less.
I was surprised by the film in the end, and I'd recommend seeing it at least once. It's a sick movie, more snuff than horror, so if you thought something like 'Saw' was bad, you'll want to avoid this.
Oh yeah and despite the fact that I went to an 11:30 showing, and the nature of this film, there was a stupid bitch who brought her kid to this who sitting infront of us and the kid could have been no older than 5 and he behaved, but still find a babysitter you whore ... If you didn't want that kind of responsibility, you should have kept your legs closed or put him up for ADOPTION! JESUS, I swear, the people in this country...
