I am sitting here bored as hell and came across some interesting tidbits on Reddit about the film, some aspects of which I know Dave was confused about.
http://www.reddit.com/r/movies/comments/lwh1u/just_watched_let_the_right_one_in_and_had_a_theory/
Some of the comments provided some interesting insight into some things I either forgot that were in the Swedish version or didn't know.
The biggest thing I didn't realize or just didn't hear: Owen's last line in the film (when they're on the train and he's eating the candies) is "Eat one now, save one for later"
To me that makes the film a million times creepier and pretty fucking awesome.
