I didn't wade through this entire storm, but I feel like too much energy is being used trying to "fix" things. It's a common issue I have with creative teams, even though I get that it would seem to be the working solution to the problems they are dealing with.
The fact of the matter is that Marvel got lucky with their initial lineup. Not all luck, because they put the people in place to work with what they had. But succeeding with the Avengers was something that even they didn't expect to do on the level that they did it. And maintaining that was even a bit of a stretch.
The worst mistake that you can make is catching lightning in a bottle and then believing that you actually made that happen. You can't just grab another bottle and do that shit again. You still have to be careful with your product.
That said, I actually enjoyed there being a lot of new content out there. Some of it worked. Some of it didn't. But I didn't feel like I had to intake all of it in order to be successful. I also didn't feel like I had to personally enjoy each and every endeavor for the company to be successful. I feel like the semi-toxic fanbase is rearing its head, and you never want to fall into the trap of giving people what they think they want, because you run the risk of pleasing the wrong people, or trying to please people that will never be happy.
