At first I wasn't fond of the backdated transformations, but the threat of death from too many transformations ramped up the drama. New transformation animation would have been nice, but the earning potential for Bandai is probably much lower than a main Precure series.
Including Michiru and Kaoru was a great idea. Their outsider perspective made their tube channel more popular.
The eco theme was heavy-handed, but handled well at the end. I liked how they worked Bunbee in at the end. The end was realistic, with some people not giving a crap, some losing interest, and some continuing to work to make things better. (cont)
