These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Sera Myu
Big Lipped Alligator Moment: The use of Chou Bi! Uranus to Neptune (Super Beauties: Uranus and Neptune) seems to stick out during Last Dracul as the lyrics include references to searching for the 3rd talisman and following the Holy Grail, despite them knowing Pluto, who's had the 3rd one from the start and the Holy Grail not at all being referanced in the plot. These lines are not remarked on at all by anyone. The only change is the removal of a reference to Infinity Academy and replacing it with them rhetorically asking if their journey was almost over.
Sailor Moon confronting vampires with the ultimate weapon: milk.
The Sailor Moon Stage musicals are littered with hilarious puns. Though, if you don't speak Japanese, you probably won't get them, as they aren't translated well in the majority of the fansubs.
Almost everything that the First Stage Starlights do.
Crowning Music of Awesome: Well, they are musicals. A few songs usually mentioned in passing include Innocent Demand, La Soldier and Drive Me the Mercury.
Damsel Scrappy: Chibi-Usa. In just about every. single. play. she appears in.
Ensemble Darkhorse: Loof Merrow and her pirate band from the Final Stage is far more developed than the group first introduced in the First Stage. To the point where they add a fifth (female) character and gave the whole group various little individual nuances, transforming what had been a bunch of idiots with an exasperated princess to an actualthreat.
Fan Nickname: Sera Myu comes from ミュージカル美少女戦士セーラームーン (Myujikaru Bishoujo Senshi Se-ra- Mu-n), the Japanese name for the stage musicals.. Also the Fan Kan events held to promote the musicals (and often preview new songs), comes from Fan Kansha, literally "for the the fans".
Les Yay: The longest running Uranus and Neptune actresses, Nao Takagi and Yuuka Asami respectively, have stated that scenes were written just for them, likely for this reason. One set of the characters also did a quick kiss on stage.
To be expected in La Reconquista, since all of the characters (including the male love interests) are played by women.
Recycled Script: Queen Beryl coming back. Seven different times. And Galaxia coming back and teaming up with Queen Beryl four times.
Tear Jerker: Most deaths end up being this. Also, if Prince Demand's monologue-thing near the end of Ankoku no Princess Black Lady doesn't make you cry, you have NO. SOUL.
Most of the fandom had this in spades when Miyuki Kanbe died due to a heart attack.
In La Reconquista, Zoisite and Ami actually develop romantic feelings for one another...and then in a flashback to the Silver Millenium, we see that they were in love back then too, and Zoisite warned Mercury that Earth was planning an attack on the Moon Kingdom, and told her to go warn the others. He ended up being stabbed to death by his own teammates moments later, and died whispering Mercury's name. And then in the present day, the same thing happens...
They Changed It, Now It Sucks: Amazingly averted in most instances. Some later actors are even considered on par or better than their predecessors.
