I just finished watching this. I think it's great: 8.5/10. This show is like a combo of Batman: TAS and The Batman (2004), like another poster said.
I really wish there were more than 10 episodes, though. Why do recent action cartoons have such short season lengths? SMH.
Anyway, I originally thought that "D!cky" was a young Bruce Wayne (like it was a flashback episode) and was confused. It turns out that I'm partially right; it's a young D!ck Grayson, a future Robin or mini-Batman. Some of the other kids are also future Robins; I didn't catch that at first, but that's cool. There are a ton of hidden cameos in this show.
I didn't like that they killed Harvey Dent/Two-Face. I actually think that this is one of the best characterizations of Dent that I've seen. So that sucks.
The Joker reveal was cool. Also, I would love to see Caped Crusader's interpretation of other Batman villains like Bane, Poison Ivy, Riddler, and Mister Freeze.
