The movie does feel lightweight. My other problem with the film is that I don't think that it breaks any new ground. Everything that is done in this movie has been done before. It might as well be an episode of Buffy The Vampire Slayer, which is actually a far better show than most people realize. Only a few Buffy fans like me understand its greatness.
There are many elements in the first film that are repeated in the remake but done better.
Despite my complaints, there is enough action in the film to get me caught up in the story. At one point there is a battle between the vampire and people in a car. The car loses. Later, there is a subterranean battle between humans and vampires that is pretty well done.
I like seeing David Tennant playing an actor and reluctant vampire expert. Too bad he left Doctor Who for this.
