...at movie adaptations have on some characters. In the comic books, each character has about 5 different, rebooted origins. If you don't mind those changes, then what's wrong with a director changing it up a little? Creative freedom is what makes movies unpredictable and impressive. If a movie came out as a frame by frame version of a comic book, I can guarantee that you'd all be saying, "boring, we've seen it before". I for one do not mind changes to origins or changes to what is considered canon. I have faith that Zac Snyder knows what he's doing and will make a good film, and if he's chosen to make the Joker an ex-robin, GET OVER IT!
