Idc who they cast, even if it doesn't look like him as long as they don't ruin the story like they did in the first one. Goku doesn't even know what a kiss is or marriage or girl friend but in the first adaptation they made him some hormonal teenage boy.... master roshi, kame house, I not in the middle of the city, bulma didn't discover capsuling items till dbz, goku was also a kid when meeting both yamcha and bulma, master roshi isn't some cool calm collected dude, he's a creepy comedic perv, where was krillin? Evolutions ruined dragon ball by ruining the whole story etc and trying to make it some Disney movie replica. Please just stick to story, Manga and animes are literally right there for you to source from and they legit took nothing from them in the first adaptation.
