For me it isn’t superhero fatigue as much as “oh, I’ve seen the same story a dozen times now” and “I don’t even know this superhero, why does he need a Netflix show?” fatigue. The writers seem to run out of ideas and just milk the same formula again and again.
And at the same time you get something like the new animated Spiderman movies which are a dope, super fresh new take that is oozing creativity out of every frame.
