DBS Anime goku is dumb, becouse the anime is aimed at toddlers, most fans who like the Anime are like 14 year old kids........I'm old and I like the anime itself, but the DBS Manga, specially with Moro and Granolah is peak, and Goku is actually normal there, not dumb or whatsoever.
If the DBS Anime ever returns, I rather Toei adapt the manga and make so the Anime continuity didn't exist. They may just put the series on late schedules, but trust me it would be worth it. I'm sorry if I dissapoint some DBS powerscalers becouse there won't be the insane power creep that Toei puts in.
