Boba Fett should’ve just never showed up post-TESB.
Or pre-ESB (Clones)
Who came up with the absurd idea to make all the clones Boba Fett? Out of all the universal shrinkage in the prequels, this one has to be my “favorite.”
George was like: “Hey, so the fans all like Boba Fett right? So what if we had like millions of Boba Fetts? What if every character was actually Boba Fett?”
Seriously though, Boba Fett was always vaguely connected to the Clone Wars in some way, even before the Prequels. The marketing material around Boba Fett in the 1970s spoke of him as being associated with troopers who fought in the Clone Wars. Of course, that vague source material never suggested that all clones in the Clone Wars were Boba Fett clones. Because that would be stupid.
Amazingly, AoTC took this vague backstory and somehow produced the least interesting possible story.
