for now, except the main batman title by snyder and cappulo, i have been disappointed in the rest of the batfamily: catwoman, suicide squad and batgirl. Okay maybe not the cliffangher from batgirl.
the most funny is nightwing who prefers to fight lady shiva that to search the joker maybe because he understood he doesn't have to hide cause he will come for him.
So if you only have to buy 1 book to follow the main story, it's batman, you can forget the others. Same thing they did with the court of owls.
