Not sure what else you expected even as arcs goes. Everyone ends up pretty much where you expect, maybe with a little luck sprinkled over some of them. Show is part historical so there's not much they could do about the big antagonist they built up in s3 but they did a good job of wrapping the bigger stuff up. Drunks are still drunk, stubborn assholes are still stubborn assholes. It was nice to say hello again, and goodbye.
Historical context is surealy limiting what Milch could do, and it's not like i was expecting them to do crazy things in that sense, but the more i think about each character's "epilogue", the more i feel like, it's exactly what they had established in the last season already.
As i said it felt more like a "check in" with the characters, more than a vital puzzle piece that was missing from the plot.
Which is alright, as i said it still made me emotional to be there again.
If you compare it to something like Twin Peaks (either FWWM or season 3), it's much more conservatively adding to what we already had.
