Some people might go into detail about this movie. Personally, I'm not going to do that. The less you know about this movie going in, the more you'll enjoy it. All I'll really say is that it's one of the best mystery movies you'll ever come across. You'll never quite understand what's truly going on, until the conclusion. If you think M. Knight Shyamalan is the king of twist endings, you need to check out Identity. It beats Shyamalan twist endings up, and steals their lunch money. Very enjoyable flick, I got the DVD so all my friends could check it out. Absolutely give this one a watch.
