By my favourite Korean director Chan wook park, and Mia wasikowska is ever more wonderful young actress, but besides some good tense psychological scenes (its a dark triller), its doesnt really stand up to the directors Korean work. Get what he was trying for, but it dragged on way too long that made it harder to really get immersed into the story, though the best scenes were engaging enough. Perhaps I shouldnt have had such high hopes, besides an Ang Lee work here or there, my prefered asian directors dont tend to fit too well in their style with western/american work.
P.S I'm going to semi-spoiler you and make it clear it has NOTHING to do with vampires, despite the name of the movie.
