The film is a waste of time. Sandra Bullock plays an irritating character compounded with bad acting (she should stick to comedies). Clooney plays a typical Hollywood cliché hero with some of the worst lines i have had to endure in a long time. No plot, no special effects, no direction, just very predictable. Waste of time and money. In this day and age of technology I have higher expectations. This film comes out of nowhere and goes nowhere. There has not been much thought about plot or depth of any character,considering there are only two actors!!!! I would not even class this film as science fiction as there is nothing very innovative nor any attempt to stretch your imagination.
