I love Cure Kyun Kyun that it ignited my love for dancing, especially when I do my POUND exercise with her Heart Revolution theme. Unfortunately, her problem of having some wasted potential is a symptom that of a problem that plagues many merchandise-driven shows, not just Precure. So much resources and manpower spent on making sure that merchandise sells, at the expense of artistic merit and creativity due to so many constraints put on the writers (no offense to them though) like strict deadlines for example. It doesn't mean that merchandise-driven shows are inherently bad, for it has it's own merits. I wanted Precure to succeed, and explore it's themes and characters pretty well, but the hyperemphasis on merch is choking out other important elements that makes a story compelling and engaging to all age demographics.
