Sat down to watch this after hearing some good reviews from friends. While it's not a total waste of time there were several things that really irked me.

It seems that several of the ideas have been lifted from the amazing work of JG Ballard (a sort of pastiche of The Drowned World and The Crystal World). That, in itself isn't a bad thing but the execution - complete with an abundance of dated CGI - cheapens the whole ordeal.

Also, I'm simply not buying Natalie Portman as a military type; poor casting. As usual she's her usual insufferable self and phones it in.

What really ate away at me was the abysmal script and delivery. The film takes itself far too seriously; riddled with atrocious and preposterous dialogue.
