I think this is what it comes down to. Not so much that they made too much content, and burned us out, because it the rush to make a huge amount of content, they absolutely let the quality slip.It's just a firehose of content. And the quality has suffered because of the need to make so many shows and movies at the same time. -The VFX has suffered. The shows exist in some kind of bizarre space- not really TV shows (most don't have a second season), and not really movies either. The stories have suffered- you have "old" characters in completely inessential shows (Secret Invasion), and new characters in great shows that just end (Ms. Marvel) and make you wonder why you took the time to invest in such a great show to begin with ... because it's not a show.
Not just of CGI/VFX either. Absolutely that's part of it - and a very clear and unarguable part - it's easy to see how mediocre-to-bad the CGI/VFX etc is in various recent Marvel movies. But more than that we've seen quality slip in other ways - whether they're as simple as not properly getting the scenes at the right level of brightness (Wakanda Forever), bad editing and reshoots - often with a confused storyline (Falcon and the Winter Soldier), weird tonal issues and rushed scenes/plot (Ms Marvel), or just outright bad shows concept-to-execution (Secret Invasion). The quality of all aspects of MCU stuff seems to have suffered. This even extends to who is being selected to write and direct movies and shows to some extent. We've seen an awful lot of directors lined up (and in some cases used) who have never directed an action project (or in some cases, never directed a good movie, or a non-animated movie), a lot of writers who are basically on their first serious project but are the main writer and so on. I think there's a bit of trying to cheap-out and have people who are controllable here. There have also been some strange diversity attitudes where instead of getting a diverse director who has a ton of experience and skill - of which there are no shortage whatsoever worldwide (I can't emphasize that enough), they prefer less experienced directors and often ones with no relevant genre experience - which tells me "controllable and cheap" are primary and any diversity is secondary for Marvel.
