I find it kind of odd that this is the franchise where we've spent the most time with Bruce Wayne and Batmans' development, but it's really more about Batman as a symbol than anything personal or the purported psychology. I think the former and its consequences will be way more interesting than Batman the character in this. Not a terrible thing as this slant has never really been done before, but a personal rivalry with the Joker will probably take a back seat to the battle of ideas. Not sure how genuine Joker's "you're just a freak, like me" is going to come across. It really doesn't seem that way to me, they've set him up as a philanthropist in a cape so far, rather than justifying the mask through some twisted psychology. His motivation for becoming Batman hasn't really satisfied me, a symbol of fear is also supposed to be a symbol of hope? Batman's the best way to go about this? Obviously not and the complicated results are interesting, but I'm not sure that's going to make up for how we got here. To me it goes beyond naivete and doesn't really make adequate sense when it's presented as something logical
