Considering that it is little more than your standard cop buddy movie, the slight variation being that the buddies are a tough seen-it-all cop and a by-the-books rookie who is an alien, Alien Nation ends up being a pretty good film. You can give a lot of credit to James Caan and Mandy Patankin for that. They have great chemistry as the partners. Both are very accomplished actors, and they make a very cliched script into something well worth watching. 7/10
