I forget where I learned about this film, which was released theatrically in the U.S. in 2008. It was made by a Swedish director, cast and crew, from a screenplay written by the Swede who wrote the novel on which the film is based. There is a dubbed English soundtrack available on the Region 1 DVD, in addition to subtitles.
A rather atypical "vampire" movie, quiet in tone and beautifully shot, in which the two lead characters are preteens (a boy who is a loner, with divorced and rather distant parents, obsessed with violent news stories, and constantly suffering at the hands of bullies at his school . . . and an androgynous young neighbor who appears to be a girl but won't admit she is, who never goes out in the daytime, who says she is "12, more or less," and who has unusual dietary needs, shall we say). This is as much a film about friendship as it is a horror film, but there is gore (tastefully done, if that's possible) and violence.
The viewer could easily come to several different conclusions about the motives of the characters and the implications of the ending, which I found to be quite appropriate.
Beware of some spoilers if you search for this film on Wikipedia or at imdb.com.
I've heard that this film is being remade by an American director for U.S. release sometime later this year. I'll be curious to do a comparison, as I will be about the terrific French thriller Tell No One (2006), which is also being re-made in a U.S. version.
