I thought the story was weak. It was not laid out very well at the start and drifted at times. It did come together better as the movie progressed. I thought the background music was terrible. Many times it actually became so loud i could not hear the actors dialogue. I loved the Science in the film and it was my only saving grace in watching this instead of leaving. The Matt Damon role was not very good as well. I thought it was added to create some drama only. Overall i would say this is a stay at home movie (DVD) but not worth the cost i paid to see it. If you love science though it may be worth seeing some of the scenes here. Very well thought out and visually fantastic.
