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.
Really, most of the songs in this series can qualify. Most notable can be the transformation theme and when the Belltier is used. Being a music-themed series sure helps.
Ensemble Darkhorse: Waon barely has any screen time, but she already has a number of fans, some of whom are very upset about her not being a Sixth Ranger.
Evil Is Sexy: Ellen at first. There are still quite a few loyal fanboys lusting over her even after she turned good.
Fashion Victim Villain: Ellen's neon-colored getup in episode 5 (temporarily) made her one of these.
Fetish Fuel: Hibiki can lick the bridge of her own nose. That's one hell of a tongue she's got.
Memetic Molester: Hibiki and Kanade, after they stripped and redressed Ellen off-screen in episode 24...
Memetic Mutation: Cure Melody's "finale" pose at the end of Pretty Cure Musical Rondo is slowly on its way of becoming this.
And then there's "Meanwhile, Siren gets hit by a car...", a phrase from the episode 10 synopsis.
Also, "Come out, NEGATONE!"
Moral Event Horizon: Subverted by Mephisto when he brainwashes Siren in episode 13; the real MEH, as revealed in episode 36, was crossed by the one controlling him during that time, the Noise of Evil.
Falsetto seems to have been crossing it over and over since taking the role of leader; however, it just may be that he had been played from behind the scenes by Noise all this time.
Ship Mates: Pairing Ouji, Kanade's object of affection, with his canonical admirer Siren/Ellen removes a blatant obstacle to the Hibiki/Kanade ship, which has been duly noted by a number of fans.
