More a long episode than anything else, Dead Zone is actually the beginning of the Dragonball Z series. Fans of the series who find themselves confused by the plot would do well to watch this (and the next view episodes) if they can find it. It establishes the fact that Goku and Piccolo, two of the show's most important characters, were once enemies, a fact that greatly affects later plot elements but is only occasionally referenced once the series gets underway. Of course, like the rest of the series, Dead Zone is light on substance and heavy on fight sequences, but that's what makes the show fun to watch, anyway. 9/10
