Lore-wise, I think it's still the best 90s season with a slight edge over Classic because everyone gets more developed backstories.
Really have to disagree with the lore part, at least for the Black Moon portion of R. While it’s nice that the 90’s anime gives us an actual explanation for how Crystal Tokyo came to be (even though it should be obvious why it was instituted in the manga as well - the Silver Crystal’s immortality granting powers were a game changer) everything else in the lore department of R is simply
dreadful, even when compared to it’s far superior manga counterpart I actually take the opposite view of you and think it’s some of the
worst that the 90’s anime done.
First off we get absolutely no explanation on the origins of Wiseman/Phantom when all the other seasonal “final bosses” at least had that much. In R it really does feel like he’s only here to be the final boss and little else - who he is and where he comes from are all completely tossed aside. (they don’t even bother giving us a short throwaway line clarifying something,
anything!) He is the very definition of “villian who’s only evil for the sake of being evil and comes out of nowhere.” He’s just completely disconnected and unimportant to even the seasonal plot and themes being set up, (love and the future) the central conflict could and
should’ve just remained on the legitimate grievances the BMC had with CT - in that maybe it was a misunderstanding all along or NQS being forced to admit to her errors in how she handled the situation and the utopian future we get a glimpse of isn’t as perfect as we thought - (in fact this would’ve been a perfect opportunity to deconstruct the very notion of a perfect/utopian fairytale like future, much like Classic before it deconstructed the idea of being a Magical Girl and having a fairytale-like past) but nope! We needed an evil nebulous boogeyman behind the scenes to be the
real source of the season’s conflict, and unlike every season before or after since this nefarious eldritch mastermind wasn’t even well-explained. (nor was he used as a clearly metaphorical device the way Chaos was used in Stars) Just some random eldritch that popped up completely out of the blue with no context given.
But what’s even more egregious of a sin to me is that 90’s BMC’s background is so effing vague and glossed over with no attempt of an explanation given (much like Wiseman’s origins) that it unintentionally makes 90’s anime NQS come off as a racist dictator. Considering this is a show aimed at
children and Sailor Moon is framed as a good role model who kids are meant to look up to, having your main lead look
racist of all things with the show never actually going out of it’s way to condemn this behavior (much less
address it or even clarify that that’s not what it was about) and even outright
glorifying our redeemed villains getting cleansed of their powers being portrayed as “the right choice in the end” is not just bad writing on a lore level, it’s an actively
offensive and
dangerous messaging being sent out to our most young and impressionable of viewers. (May I remind literal
preschoolers were watching this show!) And to think this could’ve all been avoided if the 90’s anime simply took the time to actually clarify
why the BMC’s ancestors rose up against CT in the first place or what the “cleansing” was even supposed to be about. Instead we get stuck with a vaguely prejudiced if not outright racist message being conveyed and our bad guys (pre-Wiseman) looking more like
the good guys and our
heroes the villians!
I’m all for injecting more morally grey villians and conflicts but this was not the way to go about it…
At least the anime’s lack of lore in all the other seasons - while bad writing - was inoffensive at best, here the lack of lore not only hurts the plot but manages to be offensive to boot!
R also balances the monster-of-the-day format and plot progression better than the other seasons. Classic meanders too much but benefits from mini arcs and character introductions for plot progression, and R maintains the balance Classic achieves near its end, which sadly goes out the window from S onwards. The cast was still manageable even with the addition of Chibiusa, once the Outers come in that balance is also thrown off. It's not perfect, but I believe it's the best one from that perspective.
Yeah this is what I meant when I said R also gets points for not adhering to a strict formula, it’s pacing might actually be the best from that perspective.
