I think that even the worst concept could be transformed into a good story. Just contract the right people to do the job. To say that Boba was born to be a side character just won’t work for me.
I didn’t mean to say that he has to always be a side character, I just think they chose a character that doesn’t easily fit into the role of a SW lead.
As I wrote earlier, I think they had the right idea plot-wise, but the execution was clunky.
