20 Most Rewatchable Movies Of The 21st Century

19. Let The Right One In (2008)

A deft conflation of teenage romance and vampire movie, Let the Right One In stands as one of the best horror films of the 21st century so far, in large part because it's so perfectly pitched between two such opposing genres. Director Tomas Alfredson would go on to make another rewatchable movie in good old Blighty (the immensely convoluted Tinker Tailor Soldier Spy, though that one didn't find as many fans), but Let the Right One In was the world's introduction to a filmmaker cine-literate enough to banish any groans of, "Not another vampire movie."

Adapted from the John Ajvide Lindqvist novel of the same name, Let the Right One In is a beautifully shot, less fantastical look at life as a vampire (cardboard crudely pasted over windows of the vampire home, victims' blood drained into a plastic container), and features an admittedly twisted yet surprisingly touching romance at its core.

It's one of the 21st century's most rewatchable because, in the midst of so many below-par remakes (that includes the American remake of this film, Let Me In) and disappointingly stale 'originals', Let the Right One In is a true modern classic of horror.
