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: Suite Pretty Cure ♪
Angst? What Angst?: In the final episode, even thought Hummy was unable to wake up after her Heroic Sacrifice, Hibiki is the only Cure who didn't lose her spirits, unlike her fellow Cures.
A better interpretation: Don't use music as a tool to cause people pain. All genres of music, happy or sad, are meant to be appreciated.
Crowning Moment Of Awesome: Admit it, you cheered in episode 47 when Hummy takes the Legendary Score, uses it as a shield, and THROWS HERSELF INTO NOISE'S BODY!! And inside it, she tries singing to cure all the notes he swallowed up!
Every time Cure Beat fights alone. From episode 22, 23, and especially 33.
Episode 38: Cure Muse's solo fight against a Negatone made of her orgel is rather awesome. And later, we have the Cures' gorgeous, gorgeous teamwork as they race in to save Souta. Also, this marks the first time the Goldfish Poop Gang fights the Cures by themselves, rather than relying on their Negatones and Combination Attack.
Draco in Leather Pants: Noise seems to be more popular than other Big Bads. Being voiced by Freeza and being one of the few Precure villains with reasonable motives surely helped him.
Rescued from the Scrappy Heap: Ako was originally a Bratty Half-Pint whose only main purpose was to point out the stupidity in the heroines. Come Episode 35, where she's revealed to be the masked Cure Muse, and opinions on her quickly changed. Now she's considered the most popular of the Suite Cures, as her rankings on Precure Popularity polls show.
Episode 21. Siren, under the control of the Noise of Evil, is set to sing the Melody of Sorrow and effect the whole town. Cures Melody & Rhythm are in no position to stop her, Mephisto is standing overhead waiting, and Hummy is held captive by a Bind attached to the top of the clock tower. Rather than beg or cry, Hummy simply smiles at Siren and talks about how she'll always be Siren's friend, following up by singing the song she and Siren sang together as children, making Siren remember all the good times they've had together. When she tries to then sing the Melody of Sorrow at Mephisto's order, she just can't do it; all she can do is break down sobbing.
The group transformation sequences in particular are highly praised as it created all-new sequences to incorporate the new members. Compared to the other series' cut-and-paste sequences, this is definitely an improvement.
