Holy crap this is bad, what was he supposed to be saying?
I recently re-watched the whole series (started with Kai though, since I've seen the original dub before) in japanese and I gotta say, it's fucking awesome. Son Goku's voice being high-pitched was a little jarring at first, but now I'm finishing the series up (Buu saga) and it just seems natural at this point. I also have to wonder if I went from the original Dragon Ball series, would the voice be as strange-sounding as it is at first...
And fuck I forgot how shitty dub Vegeta sounds. Japanese Vegeta is way, way better. We're talking worlds, people. And christ, the scripts. Try watching a clip of DBZ in japanese with subs, and then watch that same clip in english. It's like the english scripts were written by ten year olds or some shit. Really terrible stuff in comparison to the original material.
And I'm aware that the subs aren't 100% correct 100% of the time, but even so they're just much more depth to the writing that the dubbed version just fucking LOSES. And don't get me started on the censorship, it's fucking awesome seeing Majin Buu flip his shit and start flipping the bird to Vegito after eating him.
