Well, my first thought didn't go to the barbie-doll-esque nudity if that's what you're asking
But while we're on the subject, they already did that aaaaaaaaaaall the way back in episode 51 right before Usagi got the Cutie Moon Rod from Queen Serenity, and again in episode 151 when Ami got her new attack (the weird scene where she falls through a watery dreamscape as a naked Ami and talks to a separate Sailor Mercury). And maybe some other times I've forgotten. I think it goes on the longest in episode 200, but they didn't really show any more anatomy than they had previously, since Usagi inexplicably seems to lack certain features.
But also I'd already heard about that part in advance and wasn't surprised, so not much of a reaction there either.
I first watched the last 8 or so episodes of Sailor Stars all in one day, since they all end in cliffhangers that lead right into the next one, and the part that really slammed me in the face was episode 197/198, with what Haruka and Michiru did. By which I mean
Joining Galaxia, albeit in the vague hope of defeating her in a way that didn't even work because they don't understand these things, and going so far as to effectively kill Sailor Pluto and Sailor Saturn.
I was like "Whoa, I can't believe they
actually went that route! IT'S PERFECT! That makes so much sense with how things have gone all this time! Oh man!" And then the rainbow sparkly thing reminded me of Nephrite (and Saphir's jacket). Episode 198 is one of my favorites, actually. It was a bold story choice that made a lot of sense, but was still shocking.
It also kinda makes me think the Outers might have less team cohesion than the untainted Sailor Animamates might've, especially if half-healed Tin Nyanko is in any indicator as to what their true selves were
really like. (For that matter, half-healed Tin Nyako is another favorite moment of mine.) Especially Lead Crow and Alluminum Siren, obviously, as they've got a Zoisite/Kunzite-esque dynamic going on.
If you ever somehow brainwashed Usagi and Mamoru onto the same evil (and therefore backstabby/cold and distant) villain team, I'm sure they'd be lovingly insulting each other and helping with each others evil operations, too. And Mamoru would keep rescuing Usagi (heck, he already did that when he worked for the Dark Kingdom). Eventually Usagi would fail Beryl or whoever for the last time, and then Mamoru would take the killing blow meant for her. (Also, the Earth would probably be destroyed if any of that ever happened.)
But episode 200, specifically? I was more confused about Chibi Chibi's true nature than I expected to be by the end. I liked Usagi's forgiveness of Galaxia, and talking her down out of fighting. I always like seeing Mamoru in Prince Endymion form. I like the final conversation with the Starlights as they leave. I'm glad they put Moonlight Densetsu right at the end, that was neat.
The final closing shot, with the feather floating on the water... did that look like the stone ponds in Silver Millennium to anyone else, kind of evoking the second intro sequence from back in season 1? A very artistically intriguing thought, to me at least.
All in all, 200 was a good episode and I have no real complaints, but it's not really at the top of my favorites list. For that I'd go with 24
(Nephrite's last episode), 26
(Umino rescues Naru from Youma Boxsy), 23
(Naru protects Nephrite from the Moon Tiara), 45
(the march on D-Point), 34/35
(Usagi and Mamoru find out their true identities and the Silver Crystal appears and Zoisite dies beautifully), the R movie... and like I said above, 198 is a pretty high point. And a whole bunch of others, like episodes about Hotaru and Profesor Tomoe. And then there's the pure-comedy episodes like 31
(Rhett Butler), and... I could go on all day.
That said, the vast majority of Sailor Stars costume choices were very strange, especially the Starlight's black bikini open-fly-shorts look and Lead Crow and Alluminum Siren's bondagey-outfits open down the center of the torso with all the straps. Sailor Stars is a
little crazy even when you take genderfluid transformations and non-detailed nudity for granted
But I don't mind any of that because I'm a pervert.
EDIT: I got the "cool I'm being hugged by a naked chick and can feel her boobs" reply-posted random picture, which is
from episode 200. Awesome. What are the odds? Does anyone know the random image pool size?
