I think what bothers you it's a mix of her not taking risks musically and her general lack of depth. I mean, she has these themes she holds dear (love, friendship and happiness) and I respect her for staying true to her inspirations, but the thing is becoming a little redundant. There's only so much you can say about the same subject over and over again.
I'm lucky enough to enjoy her way of doing things and not get bored (yet). Her formula works for me. I take those little sparkles of innovation (like FANTASY and CAMERA, LIGHTS, ACTION) and I'm content.
Of course, she NEEDS to build a better stage presence. But I think she's getting better, perfomance after performance.
(And I'm stopping here, because I'm a major stan and if I keep going, I may end writing an essay, lol. Kanayan is actually my second japanese favourite singer, after Ayu! <3)
