I finished watching Sailor Moon S (also known as Season 3).
Prior to this rewatch I thought I began watching Sailor Moon in the summer of '97 when it moved away from a TV station that I barely paid attention to and changed from a weekly to a daily schedule, and that it was Sailor Moon R's Doom Tree arc that got me started. Turns out that was wrong, I'm pretty sure I started watching Sailor Moon some time after Sailor Mars joined, not with the Doom Tree arc. I'm not sure if the team was complete already. It might have been after episode 24, i.e. after Jupiter joins, but before Venus. Not that it really matters.
What does matter though is that the TV station aired Sailor Moon, R and S in one go, with daily showings and an immediate re-run afterwards, and Sailor Moon Super S, which I'm about to start soon coming a year later then. So there was a major time gap in between seasons.
What also matters in this context is that Sailor Moon S is, by far and large, the best of the seasons, and to make matters worse, the follow up Super S is easily the weakest. Now this doesn't say much because even in re-watching the show, having seen it all and being done with 127 (in words: one hundred and twenty seven) episodes the worst you get is an episode that's complete filler where a Chibi-Usa befriends a pliosaur, or one where she befriends a boy, or tries to, at least. Even those aren't bad.
They're fun to watch and unlike, say, an episode of Deep Space Nine like Move Along Home or Let He Who Is Without Sin... or any Star Trek TNG episode where Wesley shows up they never tempt one to simply skip them. Even when its bad Sailor Moon just ends up being less good.
Assuming one can get over it being anime. I know people who can't, and I get it. I tried a golly lot of times to actually get into South Park, but even though I find it generally amusing, I can't get over that art style. Or maybe the art style is just an excuse to not enjoy something that on a more rational level I know I should like but simply don't. I watched the entirety of BoJack Horseman in spite of loathing how it looks.
However Sailor Moon can be an anime that even viewers who generally don't like anime can enjoy (exhibit A, our very own Bartimaeus here). The way the people are drawn is of course typical for Japanese animation, but the art style, directions and the characters involved are noticably different, at least from other animes of the time. Presumably that was in part a reason why the show became so popular later on, a fact that 15 year old me both hated and enjoyed with a passion. It meant losing a part of nerd counter culture to mainstream, but it also meant being able to interact with fans world wide online. Something Sailor Moon shared with X-Files, another mainstay of my adolescence.
But I remember Super S having a few questionable story lines / beats.
Main TL;DR from the wall of text here: I'm not sure I should immediately jump into Super S. I'll probably ignore my own advice and just go for it, but it would probably be better to let it rest for a while. On the other hand now that I've done almost a 180 on Chibi-Usa maybe... just maybe. *pulls out discs*
Anyway, there are many reason why I think S is the best season, but mostly it was just really well written and directed, and I don't mean well written for an anime show about junior high girls in sailor suits fighting monsters. It's well written... period. Even more so when you think about how the writing team of what amounts to a low budget and mostly ridiculous anime adaptation in the 90ies managed to do here, create a plot driven by characters where actions take place and things happen because the characters involved are what they are, not what the plot dictates them to be. Yes, I'm looking at you Game of Thrones and Star Trek Picard...
Plus the new Sailor Senshi get awesome theme songs:
