Not bad if you don't care too much for the Alien and Predator franchises.

Rating: 7/10 (11 April 2006)

AVP isn't as bad to me as most reviewers here seem to think. Then again, by the time I saw this movie (just the other day) I no longer cared about the Alien series. I've never been a big fan of the Predator franchise either, though I think the Predator creature is cool.
I'll just address a few things instead of repeating what others have already said.

No element of surprise and no gore. Well, the suspense in the earlier Alien movies just wouldn't have worked here anymore; we've already seen the other films and we know what's going to happen. No gore? Well... yeah true.

Thin plot and character development. Yeah, that's one of its weaknesses. I was just getting to know the crew members when... "Huh? Dead already??"

Cool action sequences between the Alien and the Predator. Actually I thought this was pretty cool. The Predator isn't really a good guy here, but you'll wind up rooting for him against the Alien.

Concept of "Hunter's Moon." These flashbacks were pretty nice. Breeding the Alien as "the ultimate prey" for the glory of the "hunters" who wish to prove their worth is an nice idea. - Relationsip between the Predator and the heroine. The human protagonist here thinks only of how to prevent the "serpents" (Aliens) from reaching the surface and doing harm to other people. The Predator only thinks of hunting down the "prey". His x-ray vision lets him know which humans are infected with the parasite and who isn't. He spares any human that is not infected (unless they try to hurt him first). When he sees one crew member beg Alexa to kill him because the Alien is already inside him, and Alexa reluctantly shoots him, she earns the Predator's respect. He sees her as a worthy hunter like himself. Toward the end of the film when the Predator knows that more of his kind will come, he leaves a distinguishing mark on her face so that his comrades could recognize it and not harm her.

That part about the story appealed to me most. Nothing else could since the human characters weren't really developed in this film. But it's enough to make you respect the Predator and his hunter's mindset. They have their own rules, different from ours, but in a life or death situation we sometimes need to change ours as well. The tag line of this film should be, "The enemy of my enemy is my friend."
