...f the Gods is the first arc, they just add some fluff and bam, no work needed. "Dragon Ball Super Episode 05 – Decisive Battle on King Kai's Planet! Goku vs. God of Destruction Beerus" It has been done before, they use the story from the movies to make cheap/free episodes. They did it with the original dragon ball movies, and they never match up 100%. What your forgetting is that nothing is perfect. And this has been seen in the past specifically with the dragon ball franchise. I hope I'm not right, but I'm not going to bet against it.
