Sadly this is where I’m at also, and I’m a big Iger fan, I love nearly everything he did in the parks prior to the late 20teens and he oversaw a decade and a half of amazing movies (the Star Wars franchise being the one major disappointment). That said the last 5 years has been a steady decline, the parks are getting worse, the movies are getting worse, the TV shows are getting worse... they should have let him retire when he wanted to and moved on to someone with fresh ideas (not Chapek), pre 2018 Disney and post 2018 feel like 2 completely different companies.
As an Iger fan I‘d like to place the blame solely on Chapek (who took over the parks in 2018), Kennedy (who took over SW in 2012), etc but Iger lead the people who caused the decline, he owns it.
I think Disney needs a complete rebuild at the top, from the parks, to the studios, to pixar, to Star Wars, to the cruise line (the Wish is a mess), and maybe even Marvel (the one area I might leave as is). Everything has gotten worse, they need to turn this ship around quickly.
