Yeah, that back story was a huge disappointment.
I think in the extended universe Boba Fett wasn't a Mandalorian at all, but rather a guy who killed a Mandalorian and stole his armor. Pretty sure that was from the Han Solo trilogy, although it has been ages since I've read a Star Wars book.
At any rate, given that Lucas already ruined Fett's back story, I'm fine with the decision to create an original character for this show. I'd have to imagine telling the story of how Boba Fett from the prequels became a legendary bounty hunter would also require bringing back the actor that played his dad, as he was a clone of that dude, right? And that dude was lame (and probably kind of old now, which wouldn't make sense from a narrative standpoint). Pedro Pascal is way better.
I also like the post-Empire setting because it allows them a bit more freedom with where they can take the story.
First episode was good. Looking forward to seeing where this goes.
Anyone know when the Marvel shows are going to start dropping?
