In my opinion if you've seen the trailer then you've seen the movie. The effects are interesting for about 5 minutes but beyond that there is nothing to this snorefest. Maybe I missed something but then again I like a story that has more to it than something that can be written on a post it note in large writing. I don't hate this movie but if I had seen some of the more recent user ratings of this movie I would not have wasted my time, unfortunately I only saw the high rating and went with that. Usually IMDb is reliable but the current rating (8.3) seems crazy high for a movie that is so dire. I really would never watch this movie again and can only suggest that if you like to be entertained when you watch a movie then avoid this one.
