Far before the Disney acquisition, the Clone Wars tv series was actually really impressive and fleshed out the world SO MUCH. "Rebels" did the same for the original trilogy, but that might have been post-Disney.

The animators used filmmaking prowess with things like animating camera shots as if they were on a real film set, which lent a so-far unseen level of professionalism and production quality for a CG television series.

I felt so stupid avoiding it when it first got big, because I thought it was a kiddie "franchise show." It blew me away and still inspires me as a 3D artist. The visual style definitely grew on me as well. :)
