The film that puts you directly into the mind of the characters and the writer/director at the same time - you'll feel confusion and without direction. By the end you'll be giving the same answer as the movie - "I don't know!"
Not even M. Knight can say what this movie is directly about. Ask him 6 different times and you'll get 6 different answers. One could put this into the sub-genre of disaster movies, but please, someone tell us definitively what the disaster is. The best that can be done is "The trees take revenge on man for invading their environment" but that just opens up more questions that can only be answered with "I don't know!" The on-screen scientists can only say "I don't know". Wahlburg never figures out what's going on and repeatedly says "I don't know". We don't know!
