Ragnarok was like the Batman & Robin for Marvel, even worse since at least one portrayed the Silver Age with some respect. With Ragnarok I felt Taikiki or Raikiki didn't truly respect the medium of comicbooks so he made fun of everything and made everything a joke, so much so that when the serious scenes happened people didn't know if they should take them seriously or laugh. Actors just want to be themselves than actually act like the characters from the books and that may bite Marvel Studios in the ass someday they need to recast.
As some have already said, one flop and it's over but the idea of these films being amazing and flawless is very very deep into the audiences head and asshole so I doubt they are going away anytime soon. I like capeshit but their place belong in comicbooks, they are at their best there and it's annoying to have so many capeshit in not only movies but television and streaming now. Something similar happened during WWII, there was superhero craze, characters were everywhere but when that ended it almost killed the entire genre.
