This film, although billed as a sci-fi, is really about loss, mortality, apathy and love. The sci-fi element creates a canvass to show off some cgi and add a bit of adventure but little else. The science is where the film shoots itself in both feet.

The film tries to justify the plot with elements of theory which is a bit dull and restrictive; yet the story is riddled with plot holes and inconsistencies that it could have got away with if it wasn't taking itself so seriously.

The film is concerned entirely around its characters' emotions. So if a big meteor storm is on its way you will get 30 minutes of people worrying about it, 3 minutes of meteor storm then another 30 minutes of people reflecting on its aftermath. This makes a very long film feel even longer.

I found this entertaining and it is very well made with great performances and production. I found it unnecessarily long. It also suffers from crop circle syndrome – with an omnipotent technology why not just send a text and stop messing about with charades. My girlfriend didn't want to watch it but instead of hating it she was just indifferent.
