I think a lot of people conveniently forget Lucas’s impact on The Clone Wars when it comes to discourse. Lucas was at the head of the table in those writing rooms. If I’m not mistaken, most of the storylines and characters come straight from him. No episode got finalized without Lucas seeing it all the way through and approving it. That’s not to say it wasn’t a collaboration. It certainly was with all the writers, Lucas, and Filoni as director, and it was a type of collaboration not seen since Return of the Jedi I’d say.
I think you could be right, but also that a lot of people may not even know of George’s input into TCW, that they think it was Filoni as the head or being in charge of it all? Or that there wasn’t a collaboration or partnership? (why, I don’t know). It would be interesting to see a poll on this.
