I just finished Futari wa + Max Heart! Thanks for the recommendation! I'm finally a real precure fan? I can watch so many All Stars movies now...

The first half of Futari wa is extremely good. I love how different all the first-half generals are in their approach to fighting the precures, and the fights are usually more focused on them than on the Zakennas. The highlight for sure was the fight against their precure-cosplaying classmates, which might be one of the coolest fights in the series. The midseason finale is kind of anticlimactic in comparison, but at least it doesn't drag.
The second half starts out strong too; the introduction episodes for the generals made me really excited, but it feels like they didn't do anything with their human pasts and personalities, which is a shame. I would have loved to see them use their old positions and newfound powers to advance Evil King's agenda in human world.

Also, I really like Akane. She's a bit like Kaoru but a beautiful hag and senpai. Truly the best kind of character. I'm glad she got such a big role in Max Heart. Hikari is also great. I love the basic setup of Max Heart incarnating both the Queen of Light and Evil King a humans, but I feel like they just don't do enough with it? I still like how distinct Shiny Luminous is from the Precures in terms of her role in the story and fighting style.

What should I watch next? I've watched:
Splash Star -> Five+Go -> Heartcatch (best!) -> KiraKira -> Go!Pri (best!) -> Tropical -> Fresh (very best!) -> Smile -> Mahou ->Doki (best!) -> Wonderful+StarTwinkle -> Hugtto (best!) -> Suite (best!) -> Futari wa+Max Heart
If possible, I'd like something as different from Futari wa as possible. I get why FW is considered a bit of a slog.
