I love questions like this. I never collected Spider-Man, but he's still around going strong. Same with Superman. Not for more than a handful of issues depending on the creator/artist run. But Supes is still going strong. As for the movies, Avengers Endgame was the last one that I saw in the theater. At this point, I'd rather just stream the movies -- maybe -- when they become available on a digital platform. If I am representative of your typical fan, then it's a safe bet that no character can truly carry a franchise. There's something else at work here.
