My personal bias: the golden age of graphic novels was in the late 1900s, in Europe, with sublime artistry and some excellent production. At one time "bande dessinée" was considered one of the Beaux Arts in France. Then Manga came and the cheaper, high-volume flood of material, with a similar Anime presence, killed off the previous generation.
Now that we have generative AI, isn't it time to reconsider things?
