My opinion is that whether something is overrated or not is largely meaningless and that plot holes are often overstated in critiques
"Filler," too, tbh.
One of my friends at WaveMotionCannon actually used one of the anime original episodes as his argument for why "filler can be great y'all!" in an article
I'm guessing it was the famous driver's ed episode.
It was actually the Gohan return to ChiChi's in the Saiyan saga episode.
The drivers ed ep is something else though lol.
