I have no issue with the mask mouth, it's there in the 90s cartoon
Well they're aren't reusing the villains since it's the first time this Batman is facing.
Joker and Penguin are reeeeally not needed. I can understand wanting to put in Batman's first run in with the Joker, but still. Have they said anything about Harvey Dent being in this at all? I'd assume as Harvey...And not Two-Face.
Not having Harvey there would be a wasted opportunity. Again, he had a small role in AC, and he was written too much like a cliche, mustache-twirling villain instead of a conflicted, tragic one, who is capable of being both a hero and a monster.
