DragonBall Revival of F - Bardock Super Saiyan God (Thought and Discussion)

[FlashFinalVegeta]

I think it would be a great idea to add bardock into this movie. But why he's not in the movie? he could be the great next super saiyan god that includes vegeta and goku. Adding Bardock to this movie would intense the movie with new character added Why is bardock not in this movie? with so much hype for the movie you would think he will be one of the great returns to DBZ Movies!
