Pretty good.

Considering what it could have been, Alien vs. Predator turned out to be a pleasant surprise, though dragging a bit at the end. People will complain to you that the film "sucks", not because it's a bad movie, but because it doesn't 'feel' EXACTLY like the original films it branches off of.
Put it in this perspective. This isn't a Movie + Movie = Movie situation, in which case I would agree with everyone if it was. This is Movie + Movie = Comic, first and foremost, then Comic = Movie. This is a rough comic translation with of course its own differentiated setting, much like X-Men and all those other comic movies.
That put into proper light, the film does correctly portray the attitudes, touches and visual flares of both the Alien and Predator films. Knowing that AVP isn't trying to be either an Alien or Predator movie, but a look in-between, both creatures keep their character respectively well.
Next, some people say there are plot holes - mainly in the actions that some of the characters and creatures take. I guess I can't reveal spoilers on this thing, so I can't go any deeper with you. But if you really care, listen to the commentary on the DVD, and all of these questions are surprisingly answered with specific clarity.
The acting? Mediocre. What do you expect? People are complaining about the ACTING in a sci-fi action/horror film? How good was the acting in Predator? We enjoyed the originals not because of Oscar-clad acting, but because of the atmosphere they set. If you haven't seen AVP, let me put it this way: the acting is just as good/bad as Independence Day or Terminator 3. If you want something better, don't go after sci-fi action.
This is a solid popcorn film with only a tad less gore then Aliens or Predator. Remember, PG-13 can get away with a lot more these days. If you're doubting picking it up, I'd recommend it. At least rent it first.
Too many people are giving this film a bad rap. It wasn't great, but it was far from horrible, and I found it enjoyable and true to both the comics and the films. I just hope they watch their pacing and don't screw up in the Predalien for the second film.
7/10
