I think that the 3 episodes that formed the introduction movie should have been the Grevious arc that followed it... I thought that was a much better introduction to the series than the abducted Hutt one. However they would have had to introduce Ahsoka in that one and maybe it wouldn't have worked as well. But I liked all of them the first time I saw them. The Manevolence was just more intriguing to me than rescuing Jabba's son or nephew, whatever he was.
I think overall the entire series they managed to get just the right amount of General Grevious, not too much and not too little.
Maybe a bit more Aalya... the right amount of Boba/Arrua.
Gregor and Qualon Vos were under-represented.
There wasn't too much Jar-Jar but I'm surprised there was as much as there was. The female Jar-Jar was even worse, though. Was her name Bippy?
