If you were a DB fan, I wonder what you'd say about r/DBZ thinking "but it's by Toriyama and canon" is a valid defense for any literary work.

Not a DB fan but Naruto went to complete crap once the author started getting too far up his ass with the gods and destiny shit.

DB was fine until Toriyama brought it back from the dead by "blessing" it with DB Minus. It's an affront to one of the underlying themes of the Saiyan Arc.
