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.
Now, as for Anakin’s portrayal himself… I agree with G&G-Fan, to me it’s not a different and improved take on the character, but rather we’re seeing sides of him we unfortunately were not shown in the Prequels.
