Well, maybe it worked in comic book form...

Rating: 5/10 (8 October 2006)

The premise of two of science fiction's most horrific "monsters" confronting each other had been successfully maintained in a series of Dark Horse comics. Obviously, the filmmakers of "Alien vs. Predator" thought that they, too, could meld the two into a franchise built on the adversarial conflict between the two alien species. Unfortunately, the weak plot of this film and the lack of trademark gore (thus, the PG-13 rating) resulted in poor box office and an end to a possible sequel.
With the exception of Lance Henriksen, appearing in his third "Alien" film, and Sanaa Latham, the cast is comprised of virtual unknowns, and, basically serve as victims, more like the "dispendables" in a "Jason" or "Friday the 13th" flick. There is little character development.
Only does Lathan's character has a modicum of depth, and, not surprisingly, she makes it to the end credits.
Finally, this is a poor treatment of both species and should be written off as belonging nowhere in either's story lines from previous films.
