I actually think this was a pretty good special that had some good aspects about it like it's story about this Goku looking child who is the grandson of Pan. Pan obtained a illness and Goku Jr has to find out about the Dragon Balls being something he remembers knowing about from his grandmother Pan. We don't know his Father/Mother all we know is that he is part of the Son Family.
I like Goku Jr a lot, He is a timid and shy child who doesn't want to fight most of the time and was picked on and bullied by those his age and mostly wanted no trouble.
But keep in mind that Goku Jr hardly has any Saiyan genes, and that he hasn't trained much but he still has Saiyan blood in his DNA that lies a Saiyan trait is deep within him like any other Saiyan even if he is mostly a novice when it comes to battle but that's why I found him relatable.
He starts learning things the hard way even for a small child. The special is mostly about trying to overcome personal obstacles at heart While trying to uncover a spark of bravery to live up to his Saiyan ancestor such as Son Goku as well as rising above past events, not just a typical underdog story but finding a sense of connection during tough periods of time which you see from Goku jr along with unlikely company in Puck who is another good character in this.
The villains are mostly forgetful but they do harken back to some traditional enemies we had in the past of dragon ball which in turn benefits Goku Jr's first outing into unknown horizons. Some parts are left ambiguous for the viewers while watching this since this takes place far into the future of Dragon ball GT.
The artwork is really nice and the soundtrack is great.
The Ending of this is also a really good one as well that honestly makes watching this worth it.
