Snyder's overplaying the whole "You're my King and I'm your jester" element in this arc - #16 was the height of it. The concept itself is interesting, but he was banging on about it loads in interviews and thus basically gave away the entire basis of the story. He tries to make everything 'epic' but too much epic and it all becomes mundane. Will be sticking with the book anyway 'just because'.
Layman's book is much more chilled out however; it's just a really good ride.
Nightwing I pick up for an alternate angle on Gotham and because it oftens sync up nicely with Snyder's book, and I've had a soft spot for Grayson since first watching Batman Forever.
Batwing has its ups and downs, but when a decent Tinasha story comes along it's up there with the best. David is the best new charaac
I might pick up Batgirl when it fits in well with whatever Bats and Nightwing are up to, as in the current Death of the Family crossover, but no real interest in being a regular reader.
Couldn't care less about the rest of the 'family'; not because I think the books are bad, but I just don't have an interest in reading those characters.
