For a movie that aims to be realistic scientifically, it fails terribly at providing an even remotely believable premise. For example, the idea that the government would spend ~$1 billion to save single scientist from starving is simply ludicrous. The film is completely predictable with essentially no character development. It fails to even touch on the psychology of isolation and each character acts in an unbelievably selfless, upbeat manner. It's only saving grace is its reasonable acting and high budget special effects. This appears to be adequate for the mass of consumers, but anyone seeking anything more than a cookie cutter plot line will go home disappointed.
