To be honest, I saw the movie twice, with friends. Both times I watched it, it scared me. Buy a book, go out with your kids for ice cream, go to Grandma's. This movie was based on portraying the illness of schizophrenia. The real schizophrenia is much worse than what was shown I believe.
Schizophrenia is a very sad disease and in most cases the most feared psychological disease also.
I feel this movie made a mockery of it. I can't understand why some reviewers think great special effects can make up for an awful plot . This is a disgusting, violent movie. It is neither pretty to look at, nor are the ideas presented. Admittedly, the plot, characterization, and script are passable at best, but sometimes a film needs to be looked at from a different perspective than whether or not it's up for an Oscar nod, or perhaps its inclusion of violence or nudity.
