There's so many problems with the post Endgame MCU that pretty much all the complaints people make online are accurate. The poor writing/direction/CGI, the focus on lesser or uninteresting characters, modifying characters from their comic originals, the obsession with everything being interconnected and being essentially a teaser for the next product, the hubris to think that TV shows throughout the year would have the same kind of "special event" pull that the movies had on normies, the all or nothing ultimatum they have people with the expectation that everyone will watch everything they produce, the focus on self aware self parody where nothing is taken seriously, the introduction of endless universes so nothing has any gravity or meaning anymore, the pandering to small online minorities instead of to the actual audiences, the trademarked Disney+ padding that takes a 40 minute concept and drags it out over a couple of months, lack of a clear focus for the MCU as a whole, the way that the superheroes are now seen as a little more than celebrities and we see the MCU through the eyes of a Marvel stan rather than as a fly on the wall to superheroes, etc etc.
And that's before you even get to them flippantly and sexistly saying they want more women than men to make up for all the male characters they had up to Endgame?? There are great female characters, great male characters, great white characters, great black characters...we don't need them to be segregated.
