^I just don't buy that it's the characters. Go back 20 or so years and it was the DC-based films that were the box-office successes while the attempts at Marvel movies were generally bombs, like the Cannon Films Captain America
, or never got past development, like the James Cameron Spider-Man
. Marvel characters on film didn't start to work until X-Men
came out, and even after that there were plenty of failures.
Not to mention that DC's characters work just fine in a shared universe in TV animation and have done so for nearly two decades. So there's no reason they couldn't do so in film as well.
It isn't the characters that make the difference, it's just that Marvel Studios currently has a better, more focused strategy for bringing those characters to the screen. But the way things are in recent times is not the only way they can ever be. Sooner or later, WB will get its act together, and sooner or later, Marvel will lose its way. And 10 or 15 years from now, there will be people who forget their history and make sage declarations about how only DC characters are well-suited to movies and Marvel characters aren't.
