The Spanish psycho-thriller
Sleep Tight by Jaume Balaguero, clearly the more talented of the two co-directors of [Rec] and [REC]2.
For once it's a film about a psycho whose main thing isn't to kill or physically torture people. Cesar can only be happy when he makes other people deeply unhappy. As he is the caretaker of a posh apartment building, who has access to his tenant's flats, he has plenty of opportunity to ruin lives and goes about it in various inventive ways.
Excellent, a proper suspense film, very stylish and with a nasty sense of humour. If they remake it for Hollywood I can already see how different the ending will be. Loved the nasty little girl who may be the only one who is his match.
