Re: Robin or no Robin?
"Realism" has tainted superheroes and I'm sick of that question. Robin is not some huge plausibility question. It's been accepted for decades that Batman and Robin fight side by side and that Robin is a kid. The question of his safety is certainly something that can be brought up but it is not a true hurdle writers would have to jump over to put him in the movie.
Private Joker is silly and he's ignorant, but he's got guts and guts is enough.
