Outside of Joaquin Phoenixs performance, to steal a line inspired by WWE's The Rock, this movie absolutly sucks. None of the comic book Jokers themes of character were transported into this movie. (They did it for the Jack Nicholsons Joker, why not here).
Then, to make their big move, the movie makers make a mistake bigger than Marvel's Tony Stark and Bruce Banner creating Ultron (Hank Pym created Ultron in the comics), the big spoiler, he's Batmans 1/2 brother. That was their clicker, their coup de gras. STUPIDITY!
This shows that Warner Bros executives dont understand the characters they own. To us comicbok fans, this is not a golden age, this is a fleecing, where the thematic essesence of the characters that we love will never be shown on the silver screen. In that regard, DC is catching up to Marvel very fast.
