Tim Burton was more interested in the villains than Batman himself. His movies clearly show this. While Joel Schumacher may have been making a studio movie and doing what Warner Bros told him to do at the time, I think he seems more respectful and interested in Batman than Burton was.
It’s sad that he treated Batman better in Batman 89 than in the sequel. I wonder if there’s a comic of returns that better than the one comic adaptation of returns that exists out there that gives us more Bruce Wayne and Batman?
