I’ll agree he’s a decent villain, but did you really think he compares with Grand Admiral Thrawn? I thought Thrawn was great in both Ahsoka and Rebels. In the latter he was down right creepy, he’s so smart. Also I thought Ray Stevenson’s Baylan Skoll was pretty full of awesome.
I like thrawn as a villain, but never loved him.
He always felt devoid of personality and kind of one note.
I love the idea of 'supergenius villain', but they're actually hard to pull off without using the trope of 'no matter what the heroes did, it was actually always part of his plan anyway,' rather than watching things you can think 'wow, that's actually really clever'.
The closest thing he had to personality was a love of art.
Otherwise he's devoid of emotion, weakness, or anything interesting to latch on to, to make him a truly memorable villain.
The actor who played him in Ahsoka did pretty well to bring him as much life as possible.
Skoll is something else entirely. Ray's impression of him was
fantastic. I was cheering for him as much as the heroes, because there was a part of him that wasn't entirely villainous. He just felt like a decent sort on the wrong side, for reasons we didn't yet understand.
But he wasn't really... well, villainous. Loved him, but he wasn't the bad guy like Qimir was shown to be in the last episode. Skoll didn't really do anything wrong in the entire series. It's episode 5 of Acolyte, and Qimir has slaughtered his way through half the cast, all while making you question whether he's the bad guy, or was it the Jedi for bringing children to war...
