I finally got around to starting Marvelous Mrs Maisel last week. I just assumed it was going to be like Hacks and Fleabag, which were both funny shows, but it is so much more. It has the production quality of Mad Men, and after 2.5 seasons I think I would rank it pretty high up on my All Time Greats list.
(I haven't read anything online about it as I have found that no matter the show people tend to eventually turn negative towards them and I prefer to binge with no expectations. Maybe it falls off a cliff and my initial take sounds ridiculous, but so far I am loving it)
