Exactly. It's called "Superhero fatigue" but it's wildly inaccurate. It's bad movie fatigue. Not that pre-Endgame we didn't have bad films, they were just more in the beginning of the saga and people were more forgiving.

Plus it's not like the MCU was alone in putting out bad movies. We had the Sony Spider-Man without Spider-Man films (Venom, etc) and the DCEU which had great films, but more bad than good.
