Comic readers are prepared for this kind of thing. Whenever a new artist takes the reigns of a flagship character, the character's going to look different. Different is good. Different is fresh. And frankly, I love it when official movie news surprises the shit out of me. It's about the most fun you can have on the Internet this side of an age gate.
I didn't care for Man of Steel very much, I had a lot of problems with Syder's adaptation of Watchmen, and you couldn't pay me to watch Sucker Punch, but you know what? I'm excited about Superman and Batman being in a movie together. This is the kind of shit we used to dream about when we were kids and it's awesome to know we'll be alive when it actually happens. What a grand time to be a fucking nerd.
