Hopefully not. The removal of the eyebrows corrects an error during shooting of ROTJ. There are the bad changes and there are the good changes, the “eyebrows correction” belongs to the latter [edit: not “later”, otherwise you miss the incredibly funny joke below]. I don’t mind them in Rebels because they “better read in animation”.
Gotta agree with you here. it was a nice continuity change that was subtle unlike changing the emperor in episode 5, making him look awful, and fucking up his dialogue all for continuity.
