No, it is not online, at least legally anywhere. Even all the videos I tried to find of the opening credits have been pulled down by Warner Bros. But oh well. Go see it, don’t bring your kids.
I loved everything about it, the opening credits, the soundtrack, the costumes and sets, the perfect charachters – who are only perfect because they are flawed and not shiny, happy, primary coloured heros – everything.
On my way out there were some kids in front of us geeking out because they had read the comic books, which probably topped of the experience. I will read the comics, should have read them long ago.
