Not sure why you hold manga is such high esteem. As far as I'm concerned, they don't exist. Anime either stand on its own, or they don't. And you can have seinen anime based off shounen manga and vice versa.

I use Seinen or Shounen to refer to a show's target age demographic. Seinen is roughly young adult male while Shounen is adult teen male.

Oh, and K-ON!, Kobayashi's Maid Dragon, and Yuru Camp are all great, but all three are very much slice-of-life style. There's very much a difference between quite anime girls sipping tea and rarely playing some music and a cute anime girl acting as a commanding officer in a military campaign running around trying to win multiple wars while trying to battle a god-like being manipulating her from another dimension.

And, somehow, K-On just makes me depressed as f'k. Re:Zero, Code Geass, and many other anime that directly and heavily discuss depression don't hold a candle to the kind of depression I get from watching K-On. No idea why.

Kaguya-sama... I don't know. I think the story is trying to satire relational politics, but my personal family is equally as intense as the show, so it just comes off as unrealistic. Legit, I got cursed out for inviting one sister to spend the day with me and another sister, because apparently in the time I was gone, they went from good friends to fighting. Another sister yelled at me for wanting to spend time with her, because she thought I'd spend more time with her than my other family members, and that would create jealousy within the family, and then she would take the fallout from that. And then after my parents literally imprisoned me (a fully independent adult who lives out of state) for over 2 weeks, they tried to gaslight me about the whole thing. Why watch a show about a fictional character dealing with labyrinthian politics when I can just ring up family and experience it first-hand?
