I really love manga and anime, but what I love about it is mostly the drawing style and art aesthetics, particularly the older stuff that got me into it (for context, I'm talking about stuff from the the 70's and 80's because I'm old fart compared to a lot others on these forums). However, what I have come to hate about manga and anime is the grotesque over-saturation of the content into what I call high-school musicals. There's just too much focus on high-school students and high-school relationships. I don't mind that sort of thing on occasion, but anime and manga, at least much of what I see imported here to America, has become almost entirely nothing but high-school musicals. From the view of a lot of anime and manga, once you're past the age of 22, you may as well just lie down in a grave because you're life is dead anyway, nothing happens after that (true for some, not for others; depends almost entirely on how you choose your life going forward).
What I would like to see would be more ordinary stories, like just ordinary sic-fi and fantasy novels (or even ordinary drama and romance novels), turned into manga and anime. In my opinion, manga and anime are not genres; they are formats of artistic style and expressive idioms. The themes, settings, subject matter, and characters that can be portrayed in anime and manga can be damn near anything you want. It's not truly limited to all these high-school musicals with nothing but high-school students and high-school teachers. Unfortunately, over the years, anime and manga have become pigeon-holed into exactly that, the genre of cutesy high-school musicals, and I think it's a same, because, in my opinion, it's an underuse of the true expressive capacity of the style.
Occasionally, I can find a gem that expands beyond the high-school musical scenario, but it's been getting harder as the years go by.
