There’s some bad filler too though like Chi Chi and the Ox King reappearing in the Red Ribbon Army Arc, somewhat spoiling Chi Chi’s appearance in the 23rd Budokai Arc. In general though, the filler in Dragon Ball and Dragon Ball Z helps flesh out the characters by quite a bit, since the Manga is...
Just watch the movies in the order they came out in.
Movies 1-4 are in the Saiyan Arc.
Movie 5 is in the Freeza Arc.
Movies 6-9 are in the Cell Arc
Movies 10-13 are in the Boo Arc.
1. It’s too simplistic.
2. It hasn’t aged well.
3. The cash cow has been milked completely dry.
4. The franchise itself has sucked ever since GT.
5. Super killed the franchise.
I will elaborate further if asked.
