I saw this film last night on blu-ray and loved it. I'm not one for horror films normally (they're formulaic and tedious), but this one is something very special.
The IMDB page is here:
Låt den rätte komma in (2008)
The film is Swedish, but apparently Hollywood are remaking it, so you can expect a completely buggered up American attempt.
I know many people won't be interested, but I thought I'd post this for those who might be.
