Disappointing.

Rating: 5/10 (20 March 2005)

I agree with the OP. The movie lets down Alien and Predator fans alike, and definitely does not create the impact that was felt when the Alien and Predator movies were first screened.
In short: the plot is sucky, and, notwithstanding the fact that it includes two types of alien and takes place 2000m below Antarctica, it's unbelievable.
I like watching SF movies and I normally don't whinge about their content if they make a reasonable attempt at staying true to their roots (corny, but true). Unfortunately, AvP hasn't made the grade as far as I'm concerned. I was going to take the pain away by watching Resident Evil 2, but that was just as bad ....
