Thanks to the overwhelming success of the Marvel Cinematic Universe, audiences have been trained to accept that superhero characters don’t need to retire. One of the main successes of the MCU is its permanence. Like with the comics themselves, the writers will continue these stories for as long as possible. As such, the characters will be permanently trapped in their own second act. They have origin stories, they learn how to be superheroes, they develop strength and estimation, and then they stay there, unable to leave.
After a while, for superheroes, each superhero must resemble Sisyphus’ rock; On a long enough timeline, being the ultimate superhero is a symbol of futility. Since the adventure must continue (since the character is famous enough and capable enough to stay in consciousness forever), they will never be allowed to die. When a superhero is finally able to achieve their goal, it’s an aberration – and a relief.
Batman was finally allowed to leave the biz at the end of “The Dark Knight Rises.” The Eternals, after so many thousands of years of existence, have been given the gift of the unknown; Their story was finally allowed to end. “Logan” is allowed to look back on her life, see her dark past and step out with the highest dignity possible. Logan is dead. The X-Men are dead. The superheroes are dead. And the world is a little more peaceful now.
However, despite what “Logan” said, rumors abound about next Werewolves. Logan is dead, but will still be kicked and yelled at by the MCU in the second act. Wolverine will live on. That immortality is his blessing. It was also his curse.
