I disagree. I find existential meaning in the movie Saw 1-3 (I do!), and I cannot and have not found it in ANYTHING before that. The Hostel movie doesn't really have much of a meaning other than its capitalism commentary and depiction of a ultra-real situation where humans are able to do terrible things to one another.
The SECOND hostel movie showed how some of us are all talk when it comes to being tough, and that men can potentially develop misogyny for idiotic reasons that can be settled by having a spine.
OOC: I want to watch Hostel 2 again, for the scene where it shows the man who wanted to kill a woman who looks like his wife at home, with his wife in the background. I think her face was blurred, but it would be pretty 'lol wow' if the same actress was used for both characters.
