Nicely Combined Characters

Rating: Null/10 (14 August 2004)

Most movies I have seen that are based on video games have turned out to be brain fodder with the exception of "Resident Evil" and now "Alien vs Predator".
I thought they did a very nice job combining the two alien creatures into one movie, although I think I noticed on glitch in their time line.
If the "predators" only visit earth every 100 years (1904 to 2004 was 100 years) as described in "Alien vs Predator", then what were they doing here in 1987 and 1989 ? Are we dealing with two different "sects" of predators who alternate their visits to Earth ? Or what ? It was never explained in the movie.
Other than that, I loved the way the movie flowed and the way the characters eventually interacted with each other in the end. The predators, with all their advanced technology, eventually had to cooperate with us lowly humans to achieve a common goal.
I guess the moral of that would be that we should ever assume that we're superior to less advanced civilizations because we never know when we'll become dependant upon those lesser civilizations for their help or for knowledge we need.
