Query: This is not a horror movie.

This is not a horror movie- it is an interesting science fiction movie. However, it is a science fiction movie with bad special effects and a bad dialogue. The acting is good, but that just doesn't make up for it. I didn't buy this movie- I went to see it once in the theatre, and that was enough for me. If you want a real horror movie, check out The Sixth Sense.
