To be fair, you have to have an extremely high IQ to understand Go in-general. The development on a character level he and his Pokémon display is realistic and subtle, and without a solid grasp of theoretical physics most of the long-term workings will go over a typical viewer’s head. There’s also his genunine authentic childlike characterization yet level of emotion/vulnerability for a boy character and outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from the idea of having emphasis on a male character who is more “weak” but also provides drive/hot-bloodiness we’ve not yet seen in the anime in such a prominent role; this is expessed in his more androgynous (maybe to harken back to Pokémon GO) design contrasting Satoshi’s more basic blank generic design and personality inspired from Red’s, for instance.
The real long-term passionate fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these storylines and characters outside of just basic battling and streamlined fetchquest checkpoints like Badges/Ribbons, to realise that they’re not just normal victories as in achieving a goal but changing and growing as a CHARACTER (Vulnerability - Messon/Go’s crying/emotional intimacy, Hibunny - Go’s understanding of change/teamwork, Suicune/Project Mew (his strength as a fighter/ambition) they say something deep about LIFE. As a consequence people who dislike Go truly ARE idiots- of course they wouldn’t appreciate, for instance, the depth in Go and would prefer a generic energetic cute waifu like Gloria to ship Satoshi which in itself is a cryptic reference to Hayao Miyazaki’s “Anime was a Mistake” line/criticism of the anime industry and its fans.
I’m smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Daiki Tomiyasu’s love&genius unfolds itself on their computer screens. What fools.. how I pity them.
