Like my colleague Derek Malcolm, I've got no hesitation in recommending Tomas Alfredson's unnerving Swedish tale of vampirism and childhood unhappiness as this week's top film. The story, adapted by John Ajvide Lindqvist from his cult novel, and set in a timelessly bleak and snowy suburb of Stockholm, is shot through with a looming sense of menace. Initially, this is because Oskar (remarkably natural Kåre Hedebrant), the 12-year-old son of separated parents, is being randomly but ruthlessly bullied at school. But there's also a killer on the loose, and then strange, watchful Eli (the magnetic Lina Leandersson) turns up, hiding a terrible secret. The film is remarkable not just for its novel take on the tropes of blood-sucker movies, and its potent stirring ability to generate fear and horror, or even for the striking performances of the two young leads. It is also very acute about the business of being 12 - the banality of playground violence and the confusion of hitting one's teenage years. I won't say any more. Except: see it. Ideally before the planned Hollywood remake
