The first thing Batman says in the new DC universe is so... appropriate.
Justice League #1 is about what I expected. Reintroducing characters means there's a lot of talking, but the focus on introducing them to new readers means it's easy to follow and painfully obvious. Hal has to point out that he's stubborn and overly confident, they have to clarify that Batman has no powers and, yes, he's still as sociable as the original. This isn't a bad thing, but for those who already reads comics, it will feel dumbed down.
What isn't dumbed down is the art. Not only is Jim Lee the reason I read comics, but this art team -- him, Scott Williams and Alex Sinclair -- manned the first comic I ever read: Hush. The fangirlism is strong here, but even someone just picking this up couldn't deny that it's incredibly well-done. To prove it, here are the first splash pages for Batman, Hal, and Superman...
The only thing I would have liked to see here is a female character. If you're going to relaunch the universe and happen to get a lot of pressure for not focusing on female characters, wouldn't it make sense to start off with someone for females to relate to? It feels like Hal replaced Diana in this, but it's hard to say not knowing how they plan to introduce Wonder Woman. Who knows, maybe her introduction will be fantastic, maybe they're saving it for last, when there's only one female in the Justice League, there's only one chance to get it right (I'm hoping for pants here).
