If you are a film buff, literary critic, or even a fan of Japanese history you will adore this time-capsule. This is classic DragonBall with the addition of a look at the political and economic concerns of the time this piece was created. Observing the various references to fear of Industrialisation we see the Japanese rural perspective on the changes going through their country post-WW2. To see it in anime form is both surreal and fascinating to an educated person. Don't misunderstand me, it is in no way like Princess Mononoke, but it serves to be a very entertaining way to reintroduce the characters of Dragonball.
Also, I highly encourage you to listen to this with headphones, the sound of this anime is surprisingly spot-on, even by DBZ standards.
Another praise I have for this piece is that because of its time restraint it doesn't drag on (no pun intended) like the main series does in many aspects. It gets right to the point and it makes it extremely enjoyable to experience.
