Is that Danhausen in the background?
Hopefully this movie has more reason to exist than the first one did. While the first one ran alongside (and retold) the beginning of the show, this one runs alongside the arc where Gokou and Kuririn start training with Master Roshi. It's sort of a retelling but also takes things off in a different direction. I don't understand these retellings. At least by DBZ they'd start getting it right by having the movies tell completely different stories alongside certain eras of the show, without stressing over the continuity of it all. That still has issues, but at least it isn't redundant.
