There are some bad reviews written about this movie. But I think it's misunderstood by some what this movie is trying to be. Is everything that happens in the film realistic? No. It's not trying to be. Shayamalan is self aware of this, and he uses his unique style to take an intriguing story, and make it very entertaining in a way that only he can. If you go into the film with an open mind and don't let a few moments of mediocre acting here and there bother you, you'll definitely enjoy. One particular strength of the film, which is rare is find, is that it builds and builds and gets better and better toward the end. Not all movies achieve that, particularly in this genre. If you're an M Night Shayamalan fan, this movie will not disappoint. It's one of his best in my opinion.
