@Fathotel Viggo Mortensen nailed it when he spoke about it.
Toriyama has done some Lucas-esque editing though. For instance, entirely switching up the details of Goku's origin in his Dragon Ball Minus manga special. And apparently reviving Frieza in the new movie when it's been well established in DB lore that the Dragon Balls can't resurrect anybody that's been dead for a year or longer. So yeah.
That first thing apparently, yes, but the latter thing seems pure speculation right? It's not known how Frieza returns is it?
If anything it just makes DBZ even more comicbookish.
I think a core difference with star wars is that there is no canon but what one man says. Or rather now, said. It's not an adaptation, it's the direct medium and that medium is movies, not printed material.
DBZ is in essence a comic book franchise, and especially western CB fans are much more used to canon being something that can both alter and also doesn't necessarily have to matter that much. Whereas when Greedo shot first, everyone experienced that as if their Han Solo was wiped out of existence and the original scene was simply labeled 'wrong'.
That's something that's less radical with adapted material. I don't care what Toriyama does if it goes against the things I'm a fan of, I don't care about Kai either. Because I have my adaptation of the franchise in the original dubs. Even moreso for comics.
Lucas messed around in a different medium and the response was accordingly much more radical. ESPECIALLY because he refused to release the OG theatrical version, which I think is an utter **** move for people. At that point you're not just correcting your own material, you're trying to correct other people's experience, and that's that disrespectful step too far imo.
