3. Thunderbolts
The Thunderbolts are my favorite superhero team of all time. They are not number one on this list only because I am not COMPLETELY biased.
Thunderbolts is one of the few long-running comic series I've been hunting down because I love it so much. The team began as the Masters of Evil masquerading as superheroes, but when the majority of the team decided they actually wanted to be heroes for realsies, best-Avenger-ever Hawkeye stepped in to help them reform.
The series that followed was a fantastic, character-rich tale about what it means to be a hero and the possibilities of redemption. Not to mention the fact that characters like Mach VII and Songbird have been fully inducted as Marvel mainstays by now.
A Thunderbolts flick could be not only a fun, irreverent movie, but a great character piece as well. Like Suicide Squad, but with a more positive outlook.
