1) The Death Of Captain America
I think we’re all relieved in our own way that Chris Evans’ Steve Rogers is still alive and well at the end of Captain America: Civil War, but it’s still a shame that Marvel didn’t put an exclamation point on this movie by having the iconic star spangled Avenger meet his maker.
After all, he could have no doubt been resurrected somehow by the time Thanos arrives (death is meaningless in the comics, so why should the MCU be any different?), and it would have been a really shocking moment to have one of Iron Man’s energy blasts meant for Bucky strike down Steve instead.
Captain America: Civil War was never intended to be a direct adaptation, but it’s definitely a shame Marvel left out such an iconic scene.
