Is this the theme tune?http://www.youtube.com/watch?v=LIq_WmoyoRw
Nice One Mr Suit! I like it :DYou haven't given an option for if you haven't seen let the right one in but want to!
I wouldn't say don't bother, its very good, but no need for the remake in the first place. It's just not as dark.
If you've seen the original, there is no point to see the remake. It's more or less Let The Right One In for dummies. It's a good movie, but it's a good movie made out of a great movie. Literally.
Both this and Let the Right One In are worth seeing. Very atmospheric and both manage to offer the same tone throughout. This is a rare case where the remake doesn't typically follow the Hollywood trend with horror-ish movies.
Your flowchart was much cleverer and much more succinct - all I could do was rant angrily...http://www.standard.net.au/blogs/movie-reviews/why-let-me-in-makes-me-angry/2110238.aspx
