I saw AvP-R on wednesday and even though I didn't go in with high hopes, I was still somewhat disappointed.
It started off promising, but then dengenerated into a generic slasher pic with aliens.
As has been mentioned earlier, many scenes were just too dark, especially the pred/predalien fight.
Most of the characters were underdeveloped, especially the army chick.
Overall it seemed like a wasted opportunity to me. I'm sure the running time was barely 90 mins, so hopefully a directors cut is in the offing on dvd. There's def a scene or 2 in the early trailers that didnt make the final cut.
I hope this series is laid to rest now, and then maybe in a few years they can think about making a new Alien film, and bring the scares and tension back.
