Not liking it is fine. But it’s not universe shrinkage if it was always part of his lore from the beginning. It’s actually the opposite as it expanded our knowledge of the past.
George coulda’ planned for Luke n’ Leia to be brother n’ sister from the beginning & it would still make the galaxy smaller.
I don’t totally disagree with you, but Boba Fett the mystery man is much more interesting than him being part of a group who all act & dress up the same. The more we know, the less interesting he becomes.
But that’s a whole other topic.
I’m still excited to sit down n’ watch this thing!
