It would be nice to see Dragon Ball Z redone. I'd love to see it free from all of those visual inconsistencies it carries now. It would be crisp & neatly done with this age, but I'd worry about FUNi's poor actors, especially Sabat. By this age, there's more than enough money to redo the entire thing but you'd figure with DBZ's decline in popularity speeding up, even when it isn't completely dubbed yet(Movies), it may not even make much money/fan praising or whatever, as we've all seen it before--the animation would be greatly improved but it'd be nothing too new to our eyes. Hm, Budokai 3 displayed some new animation, and to be honest, the colors were nice but the animation was no better than the stuff that was done in '85, sadly.
GT is what pretty much gave DBZ a bad name--you got Goku miniaturized, which is annoying as hell--transforming in to a SS3 as a child, disregarding any previous setbacks from using the form--ridiculous power levels & transformations, which define its DROLL nature--it put to shame all of DBZ's greatest fighters and made them look like insects to the tremendously overrated & excessively exaggerated fighters it contained. I think I'd drop my passion for Dragon Ball all together if GT was every redone, in any way, shape or form.
