I haven't read Morrison's Batman. Don't get me wrong, I love the guy but, with the exception of his JLA run, I don't think his particular brand of off-the-wall insanity fits pre-established iconic characters like Bats.
Like, from what I know of his Bat-work (Creating that little **** Damian Wayne, Bruce shooting Darkseid, bouncing through time, outing himself as Batman's benefactor, forming Batman Inc. etc, etc.) I just HATE it. Those ideas just don't gel with my idea of the character or his world at all.
Basically, when GM announces a new book featuring his own characters (or characters so obsure they may as well be his own) it's probably gonna make for great comics, but when he signs up to an iconic character, I get nervous.
I'm sure this is all very unpopular and everything but that's just how I feel...
