I would say the KyoAni stuff i love Free, Sound are more dramas Liz is for sure. The ones I dislike more Maid Dragon, Chuuni etc are the SoL and also the ones getting licensed and released here.unfortunately they blow trumpets. Which is neither interesting, or sexy (unless you got some really really weird fetish)
I personally don't like sol.
I guess it depends on how much the show focuses on that central theme. Something like Haikyu is almost entirely about volleyball so is a sports anime. But something like K-on is about the girls lives and how they interact with one another more than about them being in a band. They spend more time drinking tea than playing music!I feel like slice of life is not really supposed to be about anything, it's just about daily life, so shows like Non Non Biyori.
If it's got a central theme like music band, swimming team, making anime etc., is it still slice of life?
