Go watch and read those series and come back and see what how you feel. Really , enlighten yourself and see some real art instead of kiddie bullshit like you show here.
DBZ is objectively trash. Anyone who's seen real anime like Hokuto No Ken , Berserk , Gantz , Jojo's Bizarre Adventure , City Hunter or even Naruto Bleach or One Piece knows DBZ is shit tier and will laugh in your face for saying it's good.
