>>2208671K-On isn't a bad anime... it's just moe as fuck. If you're really not a fan of the "cute girls doing cute things" bullshit, you'll not like it.
It's literally nothing but cute girls doing cute things, it's a big meme to say "oh this anime is just cute girls doing cute things" but it is never more fitting when said about K-On. It's like saying the sky is blue
