This is definitely a matter of tastes. I have enjoyed Yeoh's performance. I completely agree that I feel like we missed out of her leading a show as Prime Georgiou and would welcome that in some form.
Another great example of an irredeemable villain who somehow turned sympathetic. Loki started out as pure villain. Are audiences more accepting of him now?
I never saw Loki as a pure villain. Especially given his opening motivation was jealousy over Odin loving Thor more than him, but then Marvel plays the playground level motivations pretty hard. Now mythological Loki, he was was a total dick. Hiddleson's Loki, though, is pure rockstar sexy with the babes, of course they'd want to redeem him, I mean, only Downey's Iron Man has appeared in more movies, and for good reason.
