I could have sworn there was a Marvelous Mrs. Maisel thread here at one time, but I can't find it.
The series ended as of last night. I know the show had lost it's luster somewhere mid season 3, and that season 4 was just ok. But I've stayed with it through thick and thin and I gotta say that the 5th and final season really stuck the landing. There were lots of time jumps to the past and the "future" (no later than 2005, I think), the costumes (especially Midge's) were seriously on point, and the sets were unbelievably good. The H&H Automat set, in particular, spared no expense.
I know a lot of people (reviewers, mostly) were harping about what happened to whom and this person, and that person. But really, I feel that we know mostly what happened to the various cast, as told through flash back and flash forwards during the season.
Not going to get into spoilers here, but I found the ending to be at the same time, sweet and somewhat sad. While Midge may have not found what most of us would call true happiness, She found what she really always wanted and was ultimately comfortable and content.
