Lame Vamps
I thought this movie had a nice, straightforward premise with an interesting atmosphere and reasonably interesting characters, but the vampires just struck me as so lame.
I'm mostly tired of films where the creators feel like they have to show a facial close-up of a monster every 10 minutes with them looking at the camera and going, "Rarrrrrghh!" as though this is supposed to make them look menacing. It's become such a cliche now (especially with CG monsters though here they did it with live actors) that I think it makes them look cheesy more than anything else. I can excuse a film that does this once or twice but here I think they did it like 30 times.
I don't mind if the vampires are supposed to be beast-like. That's an interesting design decision, but I hate this recent trend where the filmmakers seem to feel that it's necessary to do this exact same monster close-up shot with a goofy pose and a growl since we tend to see it in almost every film now whether it's The Incredible Hulk or this film.
