From NetFlix:
Twelve-year-old Oskar (Kåre Hedebrant), the constant target of bullies, spends his time plotting revenge and collecting news items about the grisly murders plaguing his town. But things change when he meets a new girl named Eli (Lina Leandersson), a misfit vampire who steals his heart. As a serial killer continues to prey on teen boys in their small Swedish village, Eli helps Oskar find the courage to stand up to his tormenters.
Quiet, almost sweet, this is not your mother’s vampire film. Although made in Sweden, it is dubbed in English. The dubbed English script does not quite match the English subtitles available on the DVD.
If you want spooky special effects, you will be disappointed. This is what I have to call a “natural” vampire film. Every now and then there is some minor special effect, but that is not the point. There is not a single fang showing. Our sad forever-12-year-old girl vampire befriends a quiet and shy schoolboy who is being bullied. Yes, the poor girl does indeed drink blood and from time to time kills to obtain that blood. But she loves the schoolboy and clearly intends never to harm him. There might be one small bit of gore, but it hardly matters. To be sure I really understood the ending I had to read the Wikipedia article.
