I've binged the whole show yesterday and as I can't keep the episodes apart I'll have to give my verdict on the whole season: a bit disappointing.
It started strong but lost steam very quickly. Season 3 spent a lot of time on secondery stories - some worked, some did not and at some point Midge's mom (the actress playing her does such a great job) is not wrong when she pointed out that Midge's choices ended up affecting the whole family.
The story with Joel's club and its downstairs secret got old really fast, although I like Mae as his new GF. The Vegas wedding annoyed me and I can't figure out if they want Joel and Midge to end up together at the end of the series or not. Susi's sidegig was set up to teach her a few lessons about managing, but the Jane Lynch character is really grating. As are Joel's parents: I don't find them funny anymore.
It felt like there were more of those extended dance numbers this season and for me they tend to take the pace out of the episodes. Also, there are scene setups that are similar to AMS' other shows (the dance club Lenny took Midge too was very GG revival). On the other hand, I dreaded seeing Liza Weil in this show, but she did great, and Sterling K. Brown was a good addition too - especially when he sang on stage.
Shame that we saw so little of Lenny Bruce, but the first episode where Abe got himself arrested for standing up to him was gold. It was also nice that we got to see more of Midge's routines and how she structures them. I wonder if Abe, the theatre critic to be, will have to review one of Midge's gig in the next season.
Good to see Midge's doctor ex boyfriend again. I was almost hoping that they would get together after their blowout in the deli.
This season was set out to give Midge and Susie room to develop their skills, to learn and observe. But for an arc that comes full circle in the end, dropping them off at more or less the same stage of their careers from which they set out in the beginning, it lacked the roller coaster ride in between.
Edit: Who paid Susie's plane tickets when she went back and forth to be with either Miss Julie or Midge? Plane tickets cost a bloody fortune back then.
