Dragon Ball: Episode of Bardock
What they share
Both films are directed by Yoshihiro Ueda, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Legend of the Galactic Heroes: Golden Wings, the second film will land in a comparable space — through a different lens.
What Dragon Ball: Episode of Bardock is
You awaken on a strange planet after the tyrant Frieza destroys your home. But the world feels familiar, and so does the looming threat. The past can be a crucible. Ueda confidently directs action here. The short's bright animation style nicely updates a popular character.
