I tried searching for this so if its been talked about, I apologise.
As the first film was not so fantastic, I thought the second would bring it up a notch. As the first few minutes led on in the movie I couldnt help but feel that it was going to be as crap as the first, in which case I started losing interest, until about half way through.
Then they started tearing eachother to pieces a little more. A little more conflict, I felt a bit more excited, but it was only when the Aliens or our Predetor 'hero' was on the screen. The actors in the film didnt do much for me at all.
I liked very much the reference to Yutani, at the end of the movie, as the first did with Weyland, in a way.
Overall I say the same about the first, those movies have MASSIVE potential, and they just are not being done. Just imagine an AvP movie the size of TF, or something similair. Somebody really needs to take this series to its limits and say, this is what can happen, this is what is gonna happen, period.
Or they could get Arnold to come back for a finale Im sure that would put a lot of happiness in peoples lives. it would me.
