I watched the film today  and liked it. Quite different from the vampire movies of old and recent times, it's more linked to youth problems like the loneliness and lack of communication... and bullying, obviously, but the topic of violence is more subtle in the film. The vampire girl kills to survive and reveals this to the boy, but she points out that the boy (Oskar) would kill in revenge if he could. And both accept what the other one thinks about violence and killing.
The boring and dull population of this suburb (or city?) is more slow to understand that someone is preying on them. And the wounded blonde woman prefers death (having the courtains opened by the male nurse) to becoming a vampire herself.
Who is the man who rents or buys the house near Oskar's, and tries to forage for blood in favour of the vampire girl? I hear that, in the book, he's a pedophile guy and Eli (the vampire girl) stays with him to get protection and aid. In the end of the movie Oskar is somehow doing the same thing... so it's not about love for Eli but about raw survival: she needs "normal" allies.
Quite a lot of food for tought and pardon my bad english please
