There isn't much to tell. The Predators brought the Aliens to Earth as part of a game. It was so they could hunt the ultimate prey on a planet that they could destroy in case they lost.
I just want to say, first off, that I loved that idea. It was almost Hollywood's answer to the people who believe that aliens created the Earth and taught humans, etc. I just really enjoyed the Predator's story as the ultimate hunter, and that we just get caught up in the crossfire.
I am going to take this movie for what it was meant to be, a fan boy movie. Paul Anderson made sure this film was loaded with goodies featured in other movies (a lot of similar camera shots, etc...) and for that, I applaud him. To a purely fan boy approach, I believe Anderson did a... decent job.
The humanization of the Predator is what bugs me the most. The ultimate hunter is not one who has emotions. The Predator is a tactically superb, ruthless killer. This movie pisses all over that, making them to be some creature we are suppose to care for. Hell, I get the idea that these aren't Predators that have passed their test, but come on. The Aliens got a little better treatment, as they are the same disgusting, gooey beasts we have always known them to be. The perfect adaption as a survivor.
The second biggest flaw in this fan boy movie is the gore. Why is it a problem? There is none. I mean, sure, there is some space creature blood, but that is it. When I see these movies I want fountains of human blood everywhere. That is just something that he should have understood.
The score is uninteresting. It carries the film, but is ultimately uninspiring. The camera feels the same way. It carries the film the whole way, but really doesn't make good use of the claustrophobic temple that most of the film is shot in. I get the idea that this movie is supposed to make all of us fan's happy, but that doesn't excuse you from being boring and plain.
So with his heart in the right place, but his vision skewed, I leave you with a (somewhat forgiving)...
Notes: Aliens, Predators, and No Fucking Blood
P.S. Feels good to have a low score again.
