I've mostly enjoyed all the shows, at least more so for all them over Agents of Shield. I took a particular liking to Agent Carter though and wish we got more of that series. Loki like Dig said above, absolutely incredible. Between watching each episode myself when they came out, and watching it with friends after I've already seen it all the way through 4 times....
Wandavision was quite a good show as well but found the stark contrast between the tone of the first half and the second half off putting, and overall was disappointed that what started off as something feeling a lot "Different," ended up being more of the same marvel formula, even if it is the guiltiest pleasure of mine.
Falcon and the Winter Soldier was enjoyable since i enjoy anything Marvel, but boring to be honest. The Flagsmashers were kind of cringe. I could give a munch more indepth and less shallow analysis but don't want to bother.
What If? was alright, the episodes being so sort, they felt very rushed and as a result their is some weird discontinuity you feel in events/ the universe as a whole. Things play out in ways that don't make much sense because they can't spend several minutes on it, but only a handful of seconds.
Hawkeye has been enjoyable so far personally but can't say too much yet.
