Not style, substance. Madoka is a critique of the mahou shoujo genre, because that's what gets funded and what gets sales.
the irony when most of its plot threads and character types are derived from a played-straight tokusatsu show which is basically the male equivalent of mahou shoujo.
though that show itself riffs from battle royale
so i guess it's all good (shrug)
though tbh, it isn't much of a critique either. it's good but any psychological analysis stems from rules inherent to madoka itself. they aren't permutations of the genre itself. so it's much not of a valuable critique.
it's good tho.
or decent rather.
the writing's mostly only competent about its structure, besides how terrible the beginning is.
