I would recommend checking out the original (and IMO superior) Swedish version of the film, Let the Right One In.
As much as I liked the Americanized film, the kids in the original film were more nuanced, subtle actors and I felt the story was structured better. The climactic pool sequence was way better in the Swedish version as well.
I have to agree. The new version was certainly beautifully
shot, and the young actors were quite good... but overall I found the original to be just a little bit creepier.
Not only the execution of the pool sequence-- the brighter lighting made it SO much eerier and more unexpected than the cliched moody lighting of the remake-- but the vampire effect for the girl was a helluva lot scarier too.
