Peacemaker

Peacemaker came on cable one night. Didn't know anything about it, but boy I'm glad I stayed with it! Not only is it full of well-executed action, but the plot is ingenious - a good and a bad alien both land on earth, and each claim the other is the "bad guy" and we're kept guessing right up until end of the movie as to which is which! Not terribly well-written, but the clever idea, tongue-in-cheek tone, and quality action count for a lot.
