text: I know that so many reviews on IMDb are extreme, with reviewers either praising a film to the hilt or inarticulately tearing it to pieces. I find neither of these kind of reviews helpful, and so I do not give this film the awful review I am about to, lightly. The film is art-house science-fiction of the worst kind dressed up as a Hollywood blockbuster. The trailers draw you in by showing you what appears to be a cohesive plot, but is actually just a tiny part of a wilfully baffling series of events which are never properly resolved. I like films which challenge the viewer and I do not need to be spoon-fed a plot, and so my complaint against this film is not that it is too highbrow. No - the film is just terrible. As the credits roll you will feel genuine anger at having wasted your time on Cameron Diaz's wooden acting and a faltering plot-line. Avoid.
