It's a good rental, especially since not a lot of people saw it in the theatre. Could it have been better? Yes. Unfortunately Michael Bay was involved. If you want a critique of every Michael Bay movie ever made, rent Team America. But not the unrated copy.
Anyway the movie is has a solid premise, but unfortunately the middle of the movie is stupid. If you are told to clean something up, then destroying large swathes of Los Angeles is a bad idea. But what do I expect from the geniuses behind Con Air?
It's really much better than any Michael Bay movie has a right to be. You wont be thinking Oscar at the end, but you won't be kicking yourself for renting it either.
