I like Toriyama's attitude towards entertainment and his irreverence to coherence.
I think the original Dragonball is a legitimately well done, charming, fun, and silly show that gets a lot of things right, Dragonball Z was a lot more stupid and flawed but still in a well executed, memorable, and "mostly-charming-if-you-go-along-with-the-stupidity" way, and Dragonball Super is pure trash that I can't believe people actually like (I don't understand why it isn't viewed the same way that GT is).
A fun fact that not everyone seems to be aware of is that Dragonball actually started out as a really fun and weird "who gives a **** about anything" farcical parody of everything (like Spaceballs or something), and it's a really interesting phenomenon how Western audiences completely embraced it without ever realizing that. It's basically the Eastern equivalent to a situation where a western comic book writer comes up with a story about how a baby named Luke Skywalker from the planet Krypton landed on earth with superhuman abilities, was raised by Hobbits, finds a magical ring, and is accompanied in a fellowship of 9 warriors named after kitchen utensils and undergarments on a journey defeat Darth Vader and use the force to destroy the ring in the fires of Mount Doom (or something)..... and that story catches on, has a life of its own, and gets taken seriously as a cultural phenomenon all over the world.
Just replace Lord of the Rings/Star Wars with this even more popular classic myth (from left to right, top to bottom: Goku, Oolong, a bizarro version of Bulma, Yamcha, Goku with expanding power pole and flying nimbus, and Goku fighting Tien):
... and that's basically what Dragonball is to Japanese/Chinese people. It's pretty neat.
