Honestly, you make a fair point. I assume you're referring to the works of Satoshi Kon, Isao Takahata, and Chiaki Konaka. They have made some rather powerful, avante garde films and series. I should clarify, when I was talking about anime, I wasn't really talking about them. I was criticizing things like Gurren Lagann, Kill La Kill, and Naruto. Basically, "shonen."This is really amusing for me to read.
Most other forms of media storytelling paled in comparison, in my experience. Growing up I hated most of that sort of books that others held in high regard. Same with most movies too. They never did it for me. Always loved anime and Jrpg storytelling though.
In more modern times, I have found aspects of anime being adopted in westerner media, a prominent example being the character Syl from the Stormlight Archive, which in my head is basically an anime character when I picture her actions.
Simply put, I never really cared about all that other sort of storytelling, and only by it adopting anime and Jrpg components has it managed to belatedly garner some interest in me.
I ultimately find that this notion of "serious" (vs I guess non-serious?) artist is a BS one, conjured up by gatekeeping assholes who enjoy smelling their own farts and need to feel superior to you by pretending that the things that move your soul aren't art as much as the things they claim to like, despite doing just that thing which art most needs to do for you; be compelling. If something giving you shivering goosebumps and making you tear up with excitement is not "serious" then such a label is absolutely trash. (and yes, I am referring to the effects of digimon adventure 2 on a younger me here, not even a mid tier anime really lol, the last of us never got me feeling anything nearly as strong, for example)
I think this is the climate that lead me to just genuinely hate reading for the first 20 or so years of my life, only to get into it later in life due to being open-minded enough to actually try things that seem different and weird and not all that interesting on a first glance. Also a lot of anime came from books and not just Manga so that helped a ton too. Spice and Wolf is excellent to read. Anime was awesome too of course but the books have a ton more stuff going for em.
That said, to be fair, I think most JRPG's have more in common with shonen then with the aforementioned directors.
