7.5/10
I don't care what anyone says, I really enjoyed this movie (as you can see by my ranking it higher than The Village, which I also liked.)
The acting was okay, and I actually cared about a few of the characters. The Predators looked really good, as did the Aliens (especially the Queen).
I liked how they followed some of the comic book storylines. Fans clamor for those to be included, but everyone I've seen talking about the end of the film said that they hated it and blah blah this and blech that...even though they're the ones who whine for CBC (Comic Book Continuity) in films. So I say fuck them.
The story was decent to good, the action was great, and the intaglement of world history into the history of the Aliens and Predators was well done and interesting.
The only thing, in my eyes, that could have made this work better, aside from the Predators (minus Scar) not being pussies, would have been an 18-A/R rating, and a little more intensity in the death scenes/battles.
One last thing... there had better be a sequel, because the cliffhanger at the end would really piss me off if there aren't any plans for one at this time.
