A lot of people that prefer the Ocean dub over the FUNi dub will. 

I agree FUNi is a lot better, but it will be interesting to see what Ocean can do nonetheless. I too enjoyed Oceans dub of DBZ.

The old cast is better and funimation is better too

I agree 100%. Especially The Original Ginyu Forse and Frieza and Goku original Ian James Corlett. Plus my favorite Vegeta voice by Brian Drummond is an evil Sayain and feared with Brian Drummond voice verses Christopher Sabat who sounds like an old man. Not to mention Frieza Sounds like and old women with Linda Young as opposed to Pauline Newstone who is underrated as Frieza. Also Scott McNeil as Piccolo and the rest kills Christopher Sabat’s impersonations. Don’t forget the original cast had vast experience verses Funimations cast in Texas, because Ocean Dub cast majority had done Beast Wars Transformers and alot more Anime shows. Ocean Dub you rule and will always be the originals even with all the remastered versions. It was not Oceans fault why the cast recast, but Funimation splitting with Saban, who were responsible for edits. But their budget was bigger and better plus had a vast better music score with Shuki Levy’s music verses Bruce Faulconer’s.

I think you guys should do it, just like Dragonball Z Kai’s scripting and voice acting has improved, I’m a 100% sure Ocean’s have also, if you compare Frieza Saga Ocean to Buu Saga Ocean, I think Buu saga is WAY better, from voice’s to the background music. I’d say give it a shot…

I couldn’t watch the show with the sound on anymore once Funimation used their scabs, after they lost funding from Saban(and consequently lost Ocean without it). They really should have worked at securing a new contract with Ocean before re-airing the English DBZ. I don’t hate the Funi actors themselves obviously, but you could tell right away it was downright amateurish. Vegeta sounded awful-not only because his voice was blatently forced, but had this chain-smoker baritone to it which got worse as the show went on. Piccolo was the same damn voice, just more growly. Gohan apparently also now suffered from emphysema. Krillin, Bulma, and Yamcha, were annoying, and Goku sounded either robotic, or like he was going to bust a nut. Then of course were the terrible voices for the Ginyu Force, Frieza(how many Funi actors smoked?), and then the terrible re-dubs of the previously Ocean-dubbed episodes.
Also, the score used to be so tribal and majestic, yet sadistic and dramatic, but then it turned into generic rock synths, and was incoherent half the time. Even the SFX lost their impact, and balance.

Having said that, there were a few things I would have changed about Ocean’s return in the Android Saga-Finale. I hear they were very rushed in completeing these episodes, and didn’t have access to many of the Ocean actors at the time, but Cell was terrible. They should use David Kaye’s Sesshomaru voice or something for Perfect Cell, IMO. Saffron(sp?) needs to be Gohan again from start to his Teens. The person who took over around the Cell saga sounded too young, but was perfect in portraying Goten. As usual, Brian was great as Vegeta, but he sounded even younger than in the Namek days-He would do well to incorperate the more calmed Zechs voice(from Gundam Wing) into his existing Vegeta voice once he returns as a Super Saiyan. Android 18 had perfect sound, but hardly any emotion until the Buu saga; this needed to be rectified. And Kirby, I love ya, but I don’t like you as Goku. If at all possible-since Ian quit or was fired-Peter Kelamis should be recast. But I guess you could do worse than Morrow if push came to shove.
Even though this will undoubtedly be a futile post, that’s something which has been on my mind forever.
