Marvel did it right, of course, but in the beginning they had to go to some C listers to do it. That gave them a lot of leeway as to how the character behaves.
With Batman, Wonder Woman, and Superman people have some pretty deep preconceived notions of the character and it's more difficult to have an artistic license. HOW fukkING EVER, I've said this before you literally have the Bruce Timm universe right there, shout out to Dwayne McDuffie. Learn from it. JLU itself would be an immense play, bring a character like the Question to the big screen.
