I just watched the animated film Batman: The Dark Knight Returns. It's so much better than Nolan's Dark Knight trilogy. When you have an animated character in a superhero costume, they (usually) look good. When you dress up a real life person, they pretty much always look like a bell-end (in Christian Bale's case, he sounded like a bell-end as well).
I'm not really sold on Gotham, but one thing that's working for it, no one looking stupid dressed up as a giant bat. It's certainly better than Arrow and Flash with their generic looking identikit standard Hollywood twentysomething casts.
