One of the most common criticisms of Superman is that he is an unrelatable, unrealistic character. They tried to add some grit to him in Man of Steel, but it just never really played off well. By all accounts, the character depiction doesn't really get much better in Batman vs. Superman.
However, Superman is still a major IP for DC Comics, and he's still going to be a cornerstone of the Justice League franchise.
If you were in charge of creating the next Superman movie, how would you want the character to be portrayed in a way that is interesting and relatable to the general public?
