Although it probably helps if you are already familiar with the characters and storyline of the Dragonball Z series, it is not a necessity. The animation of Dragonball Z has always focused on fighting, and this movie is no exception. If you've never seen this series and you're wondering what you're missing, this is a good place to start. I also recommend seeing "Dragonball Z: Dead Zone" if you get the chance. Both are must-sees for any die-hard fan.
