My wife found this creepy Swedish Vampire film and we watched it tonight on Netflix as part of our festival of scary movies. The movie has a lot going for it, including some of the best child acting I've ever seen. It's one of the most realistic depictions of 12 year-olds I've seen, which is interesting, considering that one of them is a vampire. It's also a very moody film.
Unfortunately the film has problems. It's paced poorly, and the ancillary characters (the adults) are one-dimensional. There's a lame subplot where one of them gets bitten and becomes a vampire; everything about this plot is far below the quality of the rest of the movie. It could easily have been excised to make it better.
But for a Halloween film, it's a lot better than most.
