A pretty charming and inoffensive little adventure, but it movies a such a rapid pace and has so little time devoted to introducing and developing the characters that I imagine anyone without at least some prior Dragon Ball knowledge would be pretty lost, and because of that its probably only enjoyable as a companion piece to the TV show rather than a fully stand alone movie.
Also, while it is pretty entertaining it's hard to rate the movie too highly when it is essentially just a very highly condensed retelling of the first Dragon Ball arc, with a few minor changes and with Pilaf, Mai, and Shu replaced a different trio of villains.
