This is a film that came out today and which I caught after work. It's probably the best film I've seen this year, although to be honest there hasn't been much stand out stuff (Big Fish springs to mind though).
Anyway, if you liked Se7en, with it's dark visuals and non-hollywood ending, then this is more of the same, but much more sadistic. The guy that wrote this needs to be looked at closely as there is a very evil streak in his personality. Instead of having a serial killer, this goes one better by having the baddie put his captors in situations where they end up killing themselves. Much more inventive.
Just about every horror movie, that has come out in the last couple of years, have been marketed as being "the scariest thing since......
Anyway I really like this film. I'm thinking on going to go and see it again, if only to spot the clues to the ending which I'm not going to give away here.
