What do you watch when nothing else goes on? There's always a CGDCT nowadays. And for an empty season's fodder, Comig Girls do not disappoint (h/t DiGiKerot). I just wish they didn't make poor Kaosu to cry so much. Her self-doubt and imposter syndrome are familiar and even endearing, but she is also badly neurotic about it.
Thematic concerns were ever-present, but never catastrophic.
Production values were quite impressive in the beginning. But the 3D got out of control by the end. Probably production difficulties, as explained in Shirobako ("Can we make 100 horses in 3D?").
