Alien Vs. Predator -- 2004 -- PG-13

This is based on the extended version DVD.

This is a movie that works as a decent action flick with bad dialogue the first time through. Once you understand the rules and storyline the movie is laying down, you quickly realize that many of the earlier scenes don't work in the storyline given. The Predators, for instance, watch the humans as they walk through the temple, and they take off as soon as the humans take their weapons. That's when the fun begins, but you learn later what these weapons are for, completely derailing that sequence. The Predators come in and attack the humans at the base camp. Then you learn what the Predators did with the humans of old, derailing that sequence and indicating that they should not have killed them. 

The first time through, it's a fun enough movie to watch, but the more you learn, the more you realize the movie makes no sense.
