Well why do you think they call it "Drag On Ball"? They have to fill 80 episodes with a saga than can be easily be told in 10 episodes. There are only two anime who can drag the story more than DB could: Shurato and Street Fighter - there was an episode of the Street Fighter anime series that consisted of Vega laughing and showing up his powers to Chun Li. That's it. That's the episode.

The only thing that's worth watching from Dragon Ball is the Bardock special, maybe the Future Trunks TV special, maaaaybe this last DBGT TV special. The rest is pretty much crap.
