Just had a re-watch of Requiem, well just the Wolf parts really, skipped over the human stuff.
The idea of the movie is actually quite terrifying in many ways. Xenos in suburbia, watching as a community full of people you know are suddenly being ripped to shreds by these nightmarish creatures and there's not a thing you can do. That is a scary concept but it is executed incredibly poorly in the film. Okay some power plant guy is killed whoop de doo. Those kids get killed at the pool, who were they again?
I feel this movie got the Predator right at least. He does some dumb things and deals with some truly brain-dead Xenos for opposition but he was presented well. A lone, experienced hunter that has the guts to walk right into a Xeno lair and invite them to come get him.
