I normally love sci fi movies and can't get enough of them, but this one out me off watching them for several months. Fragmented reality should have been the name. It's a thoroughly disjointed storyline that mashes your brain and makes you think who in their right mind work would think this nonsense up. It seriously made me review all imdb ratings, since I couldn't believe that some people gave this an 8, and even worse, this movie got 6.4 on imdb. Don't waste your time with this one. Such a disappointment to see how the stars like Portman fall with roles like this. She deserved better.
