I wouldn't call DBZ a soap opera.
One Piece is what one may consider soap opera for men.
Watch this clip and laugh or cry:
Something is seriously wrong with their tear ducts and sinuses for the amount of mucus and tears they produce. Were they actually crying over a boat? Thank fuck they were not on Gilligan's Island
The boat did talk, though. So it must've been justified.
There are a lot of weird commonalities in those Japanese cartoons by the way. The humongous amount of tears and mucus isn't just in that series, it's in many others, too. Along with large eyebrows and large eyes even when the characters are meant to be Japanese. Japanese kids also get to watch uncensored cartoons with heads chopped off and girls flashing their tits, scenes that are automatically censored in America when they're dubbed.
