That's a hard question to answer. Unlike most people, I don't either love or hate his work. I really enjoyed the first half of his Court of Owls arc, and the second half was merely a satisfactory ending to that.
I really wanted to like his Death of the Family arc, but so far it's not working for me. I understand Batman has his flaws and weaknesses, but he's being portrayed as kind of a helpless emotional wreck IMO. I mean, I know he's going through the whole Alfred thing, but it's still kinda hard to take in. I also don't really like his portrayal of the Joker. The Joker has always been dangerous due to how unpredictable he is, but the way he's written here, you would think he's a supergenius (on a higher level than Batman) who somehow got a hold of League of Shadows training. He's a little too powerful. His monologues also aren't really doing it for me.
That sounded kinda rant-ish, but I actually really like the guy. I think he's a great writer with great ideas. I just don't agree with all of them.
