Besides the anime having terrible visuals and stretching the story into several hours:
- Shows Vegeta convincing Whis to train him and how the Saiyans got SSJB. The training segments are the only good thing about this saga. We got nothing of that in the movie, but Toriyama said Goku went first, while here Vegeta went first.
- Tagoma lives and becomes Freeza's training partner (We never saw Freeza's training in the movie). He takes Shisami's role as the strongest soldier and stomps everyone (Unlike Shisami who was = Piccolo).
- Gotenks shows up for a nut joke and defuses right away.
- Ginyu shows up and steals Tagoma's body.
- Base Goku vs 4th form Freeza lasts like, 2-3 episodes and it's an even fight (In the movie Goku shits on Freeza). It's so long Vegeta gets pissed and attacks Goku, wasting even more time on a mini Goku vs Vegeta.
- In the movie Sorbet attacks SSJB Goku. In the anime, he attacks base Goku and there's no blood.
I'm pretty sure there's slice of life filler with Piccolo babysitting Pan. And I almost forgot that Piccolo dies, he takes a death beam for Gohan before Goku and Vegeta arrive. Worst death in the series.
