Alien vs.Predator is an almost comprehensibly silly sci-fi action\horror movie, that delivers laughs at how silly it is, and delivers plenty of cringing expressions at the movies numerous over the top gross-out moments. Still, there is no denying that, despite the unremarkable acting, convulted plot, and goofy, ridiculous special effects, this movie is still a lot of fun, and I have watched in several times already. And of course, as you can already guess, if you are a fan of either the Alien or Predator movies, you should probably have a good enough time watching this movie. Still, what is still quiet surprising about it is the fact that it would Rated PG-13, which isn't very accurate: There is frequent strong creature violence with plenty of bloody deaths and gory images that come along with it, not to mention the infrequent but strong profanity including at least 1 use of the F-word. But, if you like monster movies, you will probably have a blast.
