Every character they brought over from rebels is fucking terrible. Nothing like the originals. Well, except thrawn, at least he only looks bad. In Rebels he was an overconfident idiot too. I wish they wouldn't massacre thrawn like that. I guess Timothy Zahn is the only person who knows how to write him. Sabine and hera look, move, and act nothing like they should. Hell, even rosario is barely passable as ahsoka, but I'm giving her a pass because cartoon ahsoka was ridiculously agile. We can pretend she's old now and has back issues that the force can't fix. Maybe Ezra will be more accurate, we haven't seen enough of him yet.
All that said, once I got past the terrible casting, I was able to enjoy the show.
