I don't think its right that people keep crying saying the aliens have been reduced to fodder for Requiem. Save your judgement until you see the movie as you don't know the full story. Have we already seen Wolf pick some aliens off like nothing? Yes, but we don't know about all his struggles in the movie (hopefully). The thing to remember is that Wolf is an "elite" type predator who is an expert and for him it might be easier to kill them because he's had the experience hence the possible fodder look on the aliens part.
For AVP-R, think of it as playing a game against other people. You have your basicly player who isn't that good (human), then you have your normal player who has a better grasp on how to play thus is better and is more of a challenge (alien). But, then another person comes in and slaughers the other two because his/her skills are above and beyond because he/she has played a lot more and knows all the tips and tricks of the game (Wolf).
Now I understand there has been more clips of the movie released and I won't watch them because I rather save it for the Christmas and I don't want to read spoilers so I've stopped comming into the requiem part of the fourm for now so if the aliens really are dumb then my apologies...
So I don't think the bros. have made the aliens dumber, its just that wolf is experienced thus it reflects on his battles against the aliens. Thoughts anyone?
