I sorta like what someone else said a while back when they made the announcement, something along the lines of "he's perfect cause no one thinks he could be Batman." Honestly, I think people blow these things way out of proportions. Granted, I'm a nerd but I haven't read all the comics and such, but I've never been disappointed by a movie unless they really go off script. Maybe I'm just more forgiving then most people. I'm there to be entertained and as long as they keep the main pieces of the story there and the actors actually sound like they are being that character instead of reading a script, why should it matter?
