Tomas Alfredson's vampire film, Let the Right One In (Låt den rätte komma in), is an interesting take on an old theme, except this movie has a Swedish winter backdrop (perhaps white snow for purity and cold for dead) and tells the story of Eli, a forever 12yo vampire and her actual 12yo human boy friend, Oskar.
Oskar is a thin, pale boy, who is bullied in school. Eli tells Oskar how to stop the bullying and promises to come to his help if her advice does not work. It takes Oskar awhile to understand that Eli is a vampire, but he is already smitten with her by then. The two child actors do an excellent job and the story grabs you from the start.
The film is really a charming childhood love story, except for all the blood and violence, but then it is a vampire film too.
