On the one hand, all anime and cartoons are dubs. Duh.

On the other, I think the last decade of English dubs have mostly been brilliant. But then I thought the same for Astro Boy in the 80s or Akira in the 90s. 🤷‍♂️

Some dubs are poorly done or made bad by external factors (politics, budget, half arsed production, retconning, etc), but that’s not a problem with the practice of dubbing.
