I'm not going to do that "skip to the ending" thing with Heartcatch or Suite because, well, I actually like those shows a lot, and they have way more plot and less filler than previous Precure seasons. So here's some commentary on the Cure Beat arc and other miscellany.
-The Fairy Tones are way less annoying than the average Precure mascot, and I loved that bit where Hummy realizes that she
forgot that there's really 8 Fairy Tones instead of 7, and then this happens:

-Also loved Hummy's little Cure Muse puppet theatre, crewed by Fairy Tones.

-Cure Muse has by far the sexiest outfit in all of Precure history, which becomes extra awkward later when we find out that she's, what, 10 years old? Dammit Toei, stop putting the elementary schoolers in catsuits!
-But okay, I'm not watching this show for the cute mascots or the skintight leather — I'm watching it for the "homoerotic cat angst" as
Quaedam put it when explaining her gorgeous fanart of said angsty gay cats.
If you watch a lot of Precure, you come to expect that an average season of Precure will contain lots of gay subtext, especially between the Dark Magical Girl(s) and the heroine, provided that a DMG is present in the story. Sure enough, Suite Precure adheres to this rule, except that the DMG and the heroine in question are both mascot characters. By which I mean...

..they're freaking
cats. This show is making me ship a couple of cats. OH ANIME.
( Cut for more about GAY KITTIES )-Seiren: I don't care what happens to me! But if you hurt Hummy, I'll never forgive you!
Yep, still shipping the cats.
-Despite this show having possibly the most hideous henshins in Magical Girl history, I do like some of the other stock footage, like the Belltier attacks and the duo's Super Quartet finisher. And dang, this season's attacks really went overboard with the explosions. I approve!
-Cure Beat can play a guitar riff on her cowlick. Okay, all you other Magical Girls can go home now, because nobody is ever going to top that.
