Damn, you guys are really hating on some Boba, lol.
My 2 cents:
Favreau pitched the Mandalorian while he was mid filming in The Lion King. It was a shot in the dark idea and he was given a pretty modest budget for it. They got creative as hell with said budget and hired Fuse Technology (an LED company I admittedly work very close with) and Unreal Gaming to create “the volume,” an immersive LED paneled room that allowed them to shoot every scene in one space versus traveling crew and talent all over the world like JJ Abrams did. They literally created new technology that nobody had thought of to create a basic ass 8 or so episode tv show.
Fast forward - Mandalorian blows up. People fucking loved the child. They also now have this ground breaking new filming technique (which is still being perfected, hence some of the underwhelming sfx). They didn’t even know if there would be a second season.
Personally I think Boba is filler so they can do something epic with Mando without having to rush into it. Gives them more time to write the story and a chance to play with the new tech that they literally invented for this series.
Side note - I’ve been inside the “volume” and it is so realistic it’s very disorienting. A lot of the actors had to deal with motion sickness. Look it up on YouTube, the stuff Unreal is able to do with the LED setup is nuts.
TL;DR
I work in production so it’s not always about the writing for me.
