I fucking loved it. Bats is kind of a punk that needs a good ass kicking though. Alfred and Penguin are fucking awesome. This is kind of like the alfred from the Red Claw episodes of BTAS, only a little younger and with a limp. I liked his backstory with Thomas Wayne.
Gordon is kind of a sellout to a point at the start. Afraid of his own shadow while Babs is the exact opposite. I like that babs is friends or at least works with a certain bird of prey.
I liked all the little openings for a second book.
The real star of this book however is Harvey Bullock. Its really his book in my mind and his story is by far the best and most interesting of all the characters. He is so unlike any other version of himself that I've ever seen.
