Haha, i was thinking about the most common complaint about K-On, that they never practice their music or play that many gigs, so it's "unrealistic."
Wait, that's the most common complaint about K-On? Not that it essential boils down to "cute girls doing nothing"?
Well, that's a complaint too, but
"cute girls doing nothing" is essentially the same complaint you could apply to almost all "group of girls" slice of life animes from Azumanga Daioh, to Aria: The Animation to Lucky Star, while the lack of musical insert songs is the one specific complaint laid on K-On.
In fact, i would warrant that the ONLY reason K-On gets
specifically targeted as
the definitive "cute girls doing nothing" anime while those other ones do not (I challenge you to prove less nothing happens in those other shows
), is that people came into K-On expecting the "road to success" plot-line and got slice-of-life instead.
Hell, there's one called A-Channel, which is basically K-On with no gimmick whatsoever, and 3/4 characters could be carbon copies of K-On characters. If nothing happens in K-On, even more nothing happens in A-Channel, and unbelievably, A-Channel has
better reviews than K-On despite jack shit happening in the whole series. Maybe because people didn't come into it with expectations of anything but slice-of-life.
Actually, now that i think of it, it seems like the same reason reviewers were pissed off that Tantei Opera Milky Holmes never solved any crimes xD. Genre confusion of a slice-of-life / random gag comedy, for a detective drama in that case, so you had people watching the show who really had no business watching that genre, then complaining that it's the wrong genre basically.
