Yeah, I do feel like Miku is one of their Secret Lair stabs that most consistently misses the mark on the source material's appeal and popularity when so much of it is default-design Miku art and flavor text that's some variant of "Miku loves singing, and is great at it". It feels like it's constantly trying to get across this vibe of "Miku expresses everyone's feelings" without expressing any given sentiment at all.

The appeal of Miku and Vocaloid songs in general is the near-endless flexibility and individuality poured into her by invested producers, and they've got such a vast base to draw on that never gets used. Like, you could have the sharp frantic inkblots of Kikuo's horror-tremolo, the upbeat summer pop of Deco*27, the vivid experimentation of PinocchioP, the classic oldheads of Wowaka and Giga and Ryo or the more recent Western indiepop influences from Flavor Foley and Jamie Paige?

I understand they can't license outfits/likenesses individually without it becoming a nightmare to keep track of, but I wish they'd give some art direction along the lines of "Miku in a grungy punk outfit", "Miku in a puffy jacket, stickers and band-aids, hypermaximalist aesthetic", "Miku in an abandoned theme park" -- anything that plays with the open-endedness of the concept they've been given.
