Anime is more a medium than a genre; it's like saying one does not like claymation or live-action movies.

Please, anime today is purely for children and teenagers. The golden age of serious anime is long over.

Even then, the adult stuff was still appealing to me as a kid. Take me back to Cowboy Bebop on Toonami..

Your Name is a title that for me reminded me why I became an anime fan many years ago. In 2016 when it came out, anime as a whole was well into its slop era, but Your Name has near Ghibli tier animation and powerful emotional themes rooted in both traditional and modern Japanese culture. It was the exception that proved the rule about anime slop.

What in your mind was the golden age of serious anime? There's tons of trash today (cough 99% of isekai cough), but there was plenty of trash in almost any era of anime. How much god awful "harem anime" came out in the 90s/00s?

The ratio of diamond to coal is the point. Of course you may always find an exception, but like you say there's tons of trash today.

People consider the 80s to early 90s the golden age, not 90s/00s. It isn't something I just made up.
