I really liked the movie, but in case someone is skimming reviews wondering whether to watch it, here some points to help guide your decision making.
1. It is a foreign film with no English dub, so subtitles are a must (they've never bothered me, but I've met a surprising amount of people who basically refuse to watch anything with subs).
2. It is not a thriller/action vampire movie. It is a very dry comedy that does not have many laugh out loud moments.
3. Despite being a comedy, it is also a drama and deals with some heavy themes including depression.
4. It has some highly sexual content inter-mingled with themes of religion and vampirism that goes beyond anything you'd see in an American movie. For the devoutly religious, it might even be considered sacrilegious.
