If you get away what main stream US media wants to portray, then youâ(TM)ll find anime and manga covers as a wide range of subject as live action Hollywood films.
There is something for everyone and it covers all age ranges and interests. Of course there is stuff that is clearly 18+, whether in terms of sexuality or other content matter. Yes, there are animeâ(TM)s and mangas that go a little over the top with âoefan serviceâ.
If you want to explore anime again, then starting with the films from studio Ghibli are a good start. Many consider them in the same category as classic Disney, but so much better and thoughtful (at least I do).
BTW âoeGrave of the Firefliesâ is another good film to watch, but it will leave you traumatised.
