Recent reports that Marvel's Thunderbolts movie originally ended with the death of the team hint at what could have been an extremely exciting ending, especially for upcoming MCU character Sentry. Reports of the original ending come from The Hollywood Reporter, which states that The Bear's showrunner, Joanna Calo, has been brought on by Marvel to change the film's original script. This change is good news for fans who don't want to say goodbye to major MCU characters like Bucky Barnes and Yelena Belova, but it might be robbing Marvel of a major opportunity.
