I agree with bagpuss and kesh.
I mean w/regards to Predator the only real similarity is that they are a military unit droped off on a 'mission' of sorts and they don't really know the truth of the matter.
But I can't think of a more enjoyable werewolf movie besides American Werewolf in London/Paris and that is a fairly different type of movie.
After I watched it I wanted to go out and start a d20 Modern right then, but that was this summer on the SciFi channel and months before d20 Modern came out.
I thought it has some great lines, especially some UK verbage that us 'Yankees' don't get much exposure to, and the characters reactions to what was going on around them, especially in the farm house was pretty good.
