Well, I don't know about the movie, nor do I ultimately care at this point.
I will say that the first Aliens vs. Predator game (and the second, though not as much) was the first game to literally make me jump out of my chair and cuss out loud at the screen. What did this? Simple, the facehugger. whoopee those little ****ers are scary.
Also, the atmosphere when playing as the marine is very similar to the feel in the movie Aliens. Pretty creepy, even more so with that damn motion tracker going off all the time.
and no, I don't think that b/c a game/comic/tv show is good means that a movie is going to be good, just letting you know that the game was more than just quake with aliens and predators.
