We had a pretty good Ant-Man thread just a few days ago, his current comic is pretty good and normies like him well enough that he is getting a third movie. Ant-Man is in a good position because he is popular enough to get new good material but not so much that it becomes obnoxious making the brand feel saturated. The growth or decline of his popularity depends on the success of future projects but I'm confident that he'll do well. The MCU is one of the best things that has happened to the character, putting him in a better position that he was in say, like 15 years ago. I'm glad because i've always been fan of the little guy and him being able to get some of the spotlight is great. I'm sure that this will happen to Superman because he is an icon in popular culture that can stand the test of time and I can't wait to see more new good things with him.
