I want to thank the above debaters who mentioned the the presentation of the fights of the first film. That was an example of how to show off some predator versus alien mayhem. There a wee bit of shaky camera in the first movie, but there were more than a few payoff moments, such as the shot of the predator swinging the alien around the room by its tail (thanks for pointing that one out phazedalx).
There was absolutely none of that in this installment.
One thing i did not mention was the predator/alien creature. Is it just me or did that thing look a little...cheesy. I can't quite put my finger on it, but there was something about that creature that shouted 'low budget.'
Thanks also to phazedalx for mentioning the score. it was far, far too heavy. No sense of tension at all. Although the overall production values of the first few alien movies were hugely impressive, the score also provided a crucial atmosphere in those films. In AVPR, it was just brass, brass, and bombastic brass.
Sorry Alien versus Predator fans, but this series just isn't doing it for me. It's too bad, particularly when one considers how exciting and tension filled those early Alien movies were.
