This short is just a promotional commercial adapting Star Wars episode VII: The Force Awakens, however in a mediocre way, if episode VII is not even good, this version is worse, the designs (apparently based on BB8) are ugly and the animation is not very fluid.
This animation does not serve as an independent product, if you do not know who these characters are, you will not understand anything.
It's not the worst I've seen, but with the potential of Star Wars and Japanese animation this has a lot of potential wasted.
Even so, if you are a fan of Star Wars and the anime you should see
this short film.
May the force be with you young Padawan.
