This is not canon ( official part of the franchise ), it was made
and releasead to promote a video game and episodes are a lot shorter so obviously it was never meant for it to be a great sequel to Super. It is like a Dragon Ball anime with reductions. All of key elements are there just in reduced quantity. Animation is pretty decent considering the purpose of this anime, so is the story and the plot. Still the best part of this anime are fight scenes, they are in the main focus of the anime which is the reason why most people chose to watch it. Should you choose to watch it , just enjoy the action do not overthink.
