lets be honest, DC has failed countless times trying to tell the same stories, Marvel only needed to do it once.
a number of the Superman movies were great.
and the Batman TV series was hardly a failure. Also, the first Captain America movie sucked, the first Punisher movie sucked, have you seen Corman’s Fantastic Four? Daredevil? Elektra? The Ghost Rider movies? Spider-Man 3? The Spider-Man TV series?, X-Men The Last Stand? the Wolverine movie? the Ang Lee Hulk? those were all terrible. And Marvel still hasn’t managed to produce anything animated that even comes close to JLU or Young Justice.
