Aleien fan or no Alien fan, the film just pretty much is horrible anyway you look at it. It no better than a Sci Fi original movie. Does it deserve a boxset? NO!
My theory is that "Alien" fans, "Predator" fans, "Alien vs. Predator" fans, non-"Alien" fans, non-"Predator" fans and non-"Alien vs. Predator" fans all hated the movie because it was terrible.
