Which Superman stories never adapted into a DCAU episode or DTV movie would you like to see get done in either a show or movie?
For me:
Superman Smashes the Klan - only caveat is I don't trust the Tomorrow-verse crew to do it, but otherwise this is my biggest Superman adaptation wish.
Man and Superman - a Superman origin that skips all the Krypton and Smallville stuff and really does early days Metropolis so good. For origins it's always between this and Birthright for me.
Birthright - the other best origin.
