6. Killing Off The Bad Guys
Marvel has plenty of heroes to play with, but anyone hoping to see the Masters of Evil assemble will be disappointed. Loki is still alive, but he's one of the only ones. Look back over all eleven of Marvel's movies and there's a pretty low villain roster. And those that haven't been killed (The Abomination for example) have been left on the shelf, leaving many fans disappointed and anxious to see them again. Many superhero movies seem to struggle from this (Sam Raimi's Spider-Man movies killed off all the baddies except The Sandman), but is it really that difficult to think of a better way to handle the fates of these bad guys than death? Based on the first two Phases, apparently it is! To an audience, dependably killing off these villains feels lazy and, unlike Superman taking out Zod in Man of Steel, the ramifications of their deaths aren't felt for longer than a few moments after they happen. Captain America: The Winter Soldier baddie Crossbones coming back in Captain America: Civil War is a good start, but Marvel desperately needs to start leaving some villains alive for the sake of the future of the MCU. Fleshing out the titular superheroes is no bad thing, and the bad guys could also get that same treatment if they were handled the right way.
