I'd have to say "DYNAMITE!!!!" since I really liked this movie. Hardly any plot, mostly stream of conciousness/slice of life kind of movie, but a great character. I recommend it!
"Alien vs. Predator"
Other than the effects/thrill ride aspect of this movie, it pretty much SUCKED. I'd only recommend it if you are big into the genre, have seen all of the preceding creature movies involved, and have a sweet home theater setup. Otherwise, walk on by
