I like Batman. I'm a fan.
But I haven't really enjoyed any of the Batman films, until I saw Batman: Deadend [1] (link via Via PenguinBoi [2]). It looks like the comic book and the Joker in this eight minute film is the best I've seen on film yet. The dialog is a bit corny, but nothing worse than you'll find in any comic book, but the production values otherwise are incredible.
I just wish it was longer than eight minutes.
