Each time I see this film, I continue to be impressed. The story is not necessarily overly creative, but it is well crafted (especially the switch half-way through the movie, in which we end up with an unexpected protagonist). The gore is a pretty decent touch also. Not only that, but the movie has a pretty satisfying ending, which is rather unexpected from a movie that is as grimy as this one.
Paxton's not a character that I overly enjoy for most of the film, but his depth does grow as the story goes on, and by the end, you'd be hard-pressed to not be rooting for him. Insofar as the torture aspect, it's pretty solid. Not overdone, either. While it's definitely shocking the first time around, this movie doesn't drown itself in unnecessary gore, which I applaud it for. There are downsides present, but truth be told, I don't believe there are all that many. Only thing that comes to mind right now is that I wish some of the characters had a slower death than they did. Alas, we can't always get what we want. The ending makes up for that, though. 7.5/10 (rounded down to 7/10 to fit site's format).
