I saw the clip on Youtube as well and while i thought the voice over was an improvement the music is all wrong, and even though Ziro now no longer sounds gay he still looks gay.
I mean there is no way you can make him a green looking hutt that is older than Jabba and a scarred killer and thug while he is all purple and looks like he has make up on.
Are you going to redub the roger roger robot voices i find those extermely annoying.
And watching the tv show is hlarious as every week Grievous is incompetant and loses more ships and droids and escapes like a coward. And he is supposed to be this terrifying Jedi Killer. No wonder Anakin and Obi Wan did not take him seriously in Revenge of the Sith he is a walking talking tin heep joke.
