A beautifully crafted movie that absolutely deserved its Best Picture nomination. I mean, I knew it wasn't going to win, but I'm glad it was nominated. Because this is one of the better sci-fi films. A lot of this is thanks to the main character - he is a likable person, but not an outright hero - he's prejudiced against the aliens and sees his own needs as more important than those of anyone around him. But he's a REAL person - and it's very easy to respond to that.
The format of the movie, filming it as a documentary (although lots of it doesn't really make sense for footage to exist of this) is for the most part very effective. The ending is beautiful in how it wraps things up (and not), and the final shot is one of the most touching things I've seen in film in quite awhile. Absolutely worth seeing. 4.5 stars.
