I finished Aggretsuko S5 and all in all I would say I like it. It's a satisfying end to the series (for the most part), and I think it has a pretty nice synthesis of the overall themes it presents
I think the biggest thing I haven't liked about S4 and S5 is how Retsuko has grown farther and farther apart from her coworkers (particularly Gori and Washimi, both of whom I love). S3 had the OTM Girls, and I love them as well so that was a good replacement, but I don't remember anybody much from S4, and that revolved mostly around Haida.
But thinking about it I think it makes sense with Retsuko's character progression throughout the series. S1 starts with her as "friends" with Haida and Fenneko, but neither of them really knows the real her and she feels like she has to keep her death metal side a secret. Throughout the seasons she keeps opening up, and while her coworkers are her friends, there's more to her life now than just work. And that's nice tbh, as a 20-something kind of struggling with this myself and trying to get out of my shell it's nice to see and relatable.
Also: I saw a comic once complaining that the series likes to "reset" any major progress made in one season at the beginning of the next, and while initially I agreed with it, I feel like S4 and S5 both attempted to correct this. Idk if Aggretsuko was initially supposed to be a one and done type of thing, but I feel like S4 and S5 both reckon with what happens in S3, although they never directly make the parallel. Retsuko becomes withdrawn and subdued following her stalker attack, and while the worst part of her depression disappears, you can still see its effects later. She gets mad at Haida a couple times, but she never really goes off the way she used to. It's like after putting herself out there the way she did and experiencing such negative consequences, she tries to avoid taking up space. She says multiple times this season "I just want a quiet life" etc. etc. until finally she realizes she has to stop burying such an integral part of her and allow herself to feel again. Did they approach it the best way? Probably not. Ultimately this series is a comedy so it's not surprising, and you may say "well why include that incident at all then?", but overall I think it fits.
They also got me back on board with the Haida/Retsuko pairing. It's nice they got married. They seem genuinely suited for one another now that Haida isn't so down on himself and is supporting her (his face at that first political rally was a nice callback to S3 when he first saw her at an OTM Girls gig). I wasn't expecting huge romantic overtures after the way her romance with Tadano played out, so it was okay with me.
Anyway I really like how they captured that specific millennial/Gen Z ennui so many are experiencing rn. I think they could have set up certain plot lines earlier in the series for better payoff, but I think they did their thing well with some hiccups along the way. S5 could have been funnier, though!
At some point I'd like to go back and rewatch the whole series, but for now I'm gonna be moving on. I might try giving Gundam Wing a watch finally (it's what I thought I was watching when I watched SEED I got confused lmao), and I found Princess Tutu subbed on a Facebook page so I'd like to give that a go now as well!
Princess Tutu is amazing. I found it hard to get into at first, but I ended up loving it.
