I suspect it has something to do with Feige pushing out the Russo brothers who seemed to make most of the better MCU films (Captain America 2, Captain America: Civil War, Avengers Infinity War and End Game). After that Feige started putting out movies like the Eternals that were terrible. Nearly all of the tv shows are bad... they lost any quality control. Only Loki and Guardians of the Galaxy have been as good as the films that came out prior to End Game.
