Frieza vs Goku was the climax of that show.
Went downhill from there. But a brilliant show nonetheless.
Yep, as soon as everyone started going SS, the novelty of Goku's transformation and legendary Saiyan started to wear thin. I was initially ok with Trunks too, given his enigmatic introduction vs King Cold/ Frieza; but all the subsequent SS2, SS3, Gotenks, Cell, Buu, Gogeta fusion arse-pulls, and 30 ep. battles with cheesy back and forth dialogues were way over the top - especially when Toriyama marginalized 2 fundamental DB-verse characters, Kuririn and Piccolo. Wish he had stuck with the raw intensity of Goku vs Vegeta, and the whole Namek arc.
Did anyone know that Goku, Gohan and Goten are all played from the same actress? Yes, actress.
AFAIK, since a lot of the popular Shonen anime are several seasons long, and are aimed at the prepubescent age group with young protagonists, the voice-over is done mostly by women - because their higher pitch doesn't change that much via puberty, and the childish portrayal of the protagonist is maintained. eg. The seiyū for Luffy from One Piece (started in 1999) also did the voice-overs of Yajorobe and Kuririn (1986 onwards), and Koenma from Yu Yu Hakusho. Similar for Naruto and Sabo and Gon from HxH (Junko Takuechi). Makes sense, but totally weird at the same time.
