I’m probably one of the few people who doesn’t mind Temura Morrison. Sure he’s a prequel retcon/SE change but if you look past that he does have a cool voice.
I never had any loyalty towards Wingreen. Honestly, I don’t get it. It’s a cool voice but he’s got four lines?
As for the potential spin-off, I don’t think there’s much to worry about. Morrison’s easy to get past if you just forget why you hate him (PT/SE). Boba’s origin has already been fucked so no need to worry that the movie will do that. Besides that the character is a blank slate in the new canon so there’s a lot of room for something interesting, and finally a way for Fett to live up to his off-screen hype on-screen.
