Let me tell you a few things about
Suite Precure.
For one thing, if you like Precure for what it is and didn't just enjoy Heartcatch for the Umakoshi and sakuga, you probably won't hate this. I followed Suite every week for a year, and never had a moment where I thought "wow, this outright sucks". The first half of the series is a
lot stronger than the second which is pretty badly mismanaged for several reasons, but ultimately it does just about as much right as it does wrong.
About the monsters, I remember having a long conversation with Geneijin debating whether Negatones or Akanbe were worse enemies. The conclusion ended up being that Akanbe were more offensively ugly but the clown faces gelled more with the storybook theme of
Smile than the Negatones with their weird pterodactyl skeletons and pelvis spikes matched the musical theme in
Suite. Both Negatones
and Akanbe are a downgrade from the Desertrians in Heartcatch in that the Cures merely pound enemies into submission without having to solve some greater underlying problem fueling the enemy's rampage, but if you don't mind the battles in
Smile, you'll probably be okay with those in
Suite. There is decidedly less comic relief in
Suite's battles, however.
In case you didn't already know, Hummy's seiyuu is Mitsuishi Kotono, who voiced Usagi in
Sailor Moon. It's an interesting reversal to see the world's most famous mahou shoujo become the mascot character, and even if Hummy seems annoying now, she receives a lot more character development than the average Precure mascot, so just endure for now. Interesting fact: there's an episode in the first season of
Sailor Moon that heavily features cats (there was a fat green cat named Rhett Butler, if memory serves.) There's a moment in the episode when Usagi imitates a cat, and it's like hearing Hummy 20 years in advance. I'll try to find the exact scene for you!
The theme of music features heavily throughout the series as you'd probably expect, so make peace with it and learn to enjoy the more ridiculous aspects of Kanon Town and Major Land. The costume design for the Cures in
Suite is actually some of my favorite in the entire franchise, and while this is an unpopular opinion, I like the transformations as much as those in Heartcatch. They're not nearly as sakuga, but they're pretty damned classy. It all comes down to whether you prefer ribbons or perfume, I suppose. Suite also has
the best transformation music in the entire Precure franchise, which has a big influence on my opinion of the transformations. Admittedly, Trio the Minor are pretty hideous compared to the Desert Messengers and even Joker's subordinates and never really stop being a blemish on the show because they remain disappointingly static characters. Just try your best to find their Team Rocket-esque incompetence amusing.
Well, I've kind of talked you to death over a show that you've only seen one episode of, so I'll try not to do this again. Keep watching!
