I agree with most, only Batman I disagree
Sure the batman bad@$$ nerd meme will crash and burn soon enough (who shall replace it? I wonder)
But what I disagree with is batman as a whole crashing and burning. He is just to great of a character often supported the right way by good authors.
Batman character great(on a narrative level) for many reason, but there are 2 big ones:
1. His trama. Of all the "major" superheroes has such a richly tragic past. Sure Parker had his uncle, but that is nothing to having both parents murdered infront of you as a child. The scar will never be gone, and hinders much of any chance Wayne will ever have for a happy end. Batman takes on a Shakespearean tragedy element from this.
2. He's human. Most other super heroes are super beings or made so through technology. Batman doesn't, yet has to keep up with them. He as a human has to triumph over these incalculable obstacles through will power and intellect.
Batman had the fortune to often get writers that recognize these(and other strengths) to craft rich narrative stories(in various mediums)
Other heroes often get writters that focus mre on fan/self service. I termed it the "and then",, 1 up-manship
An example with superman(SM): He'll crush Lex's new maga death machine,
"and then" SM will crush a city sized robot, "and then" he'll crush a country sized robot, "an then...
Instead of working towards there narrative strengths(for SM, the strong defending the weak, even though they could rule them), they just have him fight stronger and stronger enemies. The internal conflict gets thrown aside for the cheaper external
In short Batman the character won't crash and burn as he has to much story potential, and writers that know how to use it.
The nerd fandom, yeah.
ANd yeah, I broke # 3 in my poorly written response
