I've been calling Boba Fatt since he pulled his robe down and revealed his identity to Mando.
But it's a term of endearment!
People get old. People get fat. Yes, there's less time between BoBF and the end of RoTJ than the ShitTrilogy, but still...dude went through a lot. He gained some weight. Lay off!
Harrison Ford stayed super slim cause he's a freak of nature. But before her untimely passing and it's wrong to speak ill of the dead, we all said some not so kind things about the state of Princess Leia.
And let's not forget Hamill had to go on a crash diet and they still squeezed him into a girdle.
I for one think Morrison's physicality looks great, especially for his age. I still prefer the "Throne Room" costume from the teaser, but the regular costume with red booties is just fine too.
Honestly, I'd be a little bored if he looked like a digital recreation of Bulloch in the suit from 1979. I'm totally fine if they do that for flashbacks, but everything we've seen so far entirely works as Fett's evolution for me.
