Wait wait wait since when was the Joker Batman's brother and why would you twist it that way they are nemesis not sibling rivals why did they think that that was a good idea to many story changes from the original comic is why DC couldn't match Marvel and this is why DC Joker was only in theaters for 2 months hell that's almost straight to DVD but hey you like change there it is it makes no sense and doesn't match anything DC every did plus let's not forget the Joker was the only villain who truly did not have a backstory
