I think Eternals gets more negativity than it deserves because it did raise some interesting philosophical questions about blindly following your leader and also whether they should interfere with life on earth or not, whether humans were worth saving and so on. Not one of the best MCU movies by any means but you compare it to Black Widow, Captain Marvel, Thor 2 or Iron Man 2 for example and it's not nearly as bad. I would say it stays out of the bottom 5 easily. I do think the MCU formula can get a bit grating sometimes (every serious moment undercut with a joke) but the biggest compliment you can give the MCU is that even the worst films (and there are a couple that aren't that great) are still enjoyable to watch the first time. I would maybe say 50% of the MCU movies fall into the category of 'fun to see once, not great enough to see twice', but that also means that the money spent on the movie ticket is never really wasted.
You compare it to something else like the X-Men franchise and that one has a couple that IMO stands up with the best of the MCU - Logan and Days of Future Past, but you also get stinkers like X-Men Origins Wolverine and Dark Phoenix that make even Thor 2 look like Citizen Kane. Morbius makes Captain Marvel feel like Infinity War in comparison.
Definitely feel more hyped for Dr. Strange 2 due to the fact Raimi is directing. One of my favorite directors and I just hope he's given room enough to 'make it his own'. That's otherwise one of my main criticisms with the MCU is that aside from maybe the Guardians of the Galaxy films, many of these films feel like they could be made by the same director. And they have their formula and it works, you don't change the recipe of the Big Mac sauce after all, but I do hope Raimi gets to play around with a creative hero like Dr. Strange.
