I would say overall it's glass half full. Here's my guide:
Black Widow: Hated it, but only because I can't stand Taskmistress. Without that, might've been decent. (But we'll never know.)
Shang-Chi: Yeah, actually pretty damn good.
Eternals: Decent if you don't consider it a superhero movie at all but I can't tell if that's really enlightened or just really pathetic.
NWH: Masterpiece but mainly because of all the characters the MCU had zero hand in, so I'm not sure how much credit they deserve.
Doctor Strange 2: On the messier side and I was kinda pissed at how Wanda was treated but still overall pretty good. (But yeah, so much for Jim from The Office as Reed Richards)
Thor 4: Good things about it, Christian Bale as God Butcher is great and a fun enough movie to watch drunk, but past that, the less said the better (and f**k Taika/Korg)
BP2: I can't really get past nose-ring Namor but other than that, it was put together well-enough I guess. Don't know if I'd watch it again though, kind of a snob film either way. Not recommended for fan-type people.
Quantumania: Minor issues here and there, but overall I honestly think it's the best Ant-Man movie.
GOTG3: Nowhere near as good as the first 2 IMO, but still good.
The Marvels: Not perfect, but was never trying to be, they just wanted to have some fun and it was fun so I'm overall satisfied with it.
