I'm a big DBZ fan, but even I can say that it doesn't need bringing back. If it was, you'd all start complaining about bad storylines and villains and how you wished that someone had done something else. Just leave it guys, it doesn't need reviving with new episodes.
No, I am a big fan of DBZ but It should stay buried and never return. DBZ died on me with GT so I dont want it brought back. It had it's run and ever since freza and broly their has not been a villain as devious and sinister as these two and their will never be.
