I don't see why it's bad. I'm intrigued into it a lot, especially with Penguin and the Mob part. That stuff was great. I'm confused why Fish Mooney want's that girl though, how is she actually a weapon? Good to see Riddler again.
I do agree on the mishandle of two-face. He's an iconic villian and yet they only use him for like, the last half hour of the movie. Seemed like such a waste. Reminded me of SM3's mistake with Venom.
