Perez' art is for kids just getting into comics. It gives them a lot to look at.
It's not bad though. I don't hate it.
The book was alright. Kind of like an episode of JLU, which is good, with some neat references to put it firmly in the DCU, which I always appreciate.
I'm really looking forward to when they get to more obscure characters or at least characters without their own titles, but I have no idea when that might be.
