There are alot of people who are fans and even collectors of Xmen stuff and media, and as long as they make movies featuring wolverine, folks will go see them. Dont know where they go now after the last wolverine movie though, or think Jackman will play him again? I knew of many comic book characters through friends etc but collected very little. X men had an awesome cartoon though, and for people now 35 to 45 years old...it was one of their or their singular favorite growing up. They will always go and see the movies, there is a connection. I am 41, my childhood saw GI Joe and Transformers as the best cartoons, weekends only was 1 episode of xmen. It was huge. Gambit was a badass in the cartoon, never developed in the movies at all...tragedy. People who arent fans of comics like Xmen in the way that Batman did in the 90s. Aquaman isn't gonna get there. Lots of others arent either sadly. The characters have to act in a way that people can identify.
