Start as Yoda you have talking Brax?
I don't know; on the one hand I'm really excited seeing as the cast looks so promising and unlike say other characters in Star Wars - Palpatine, Yoda, Boba Fett (even though we got that while we didn't want it) - I feel Han isn't that much shrouded in mystery that a backstory would ruin him.
... That being said; I heard rumors that the movie might delve into the fact that Han Solo is not his real name.
Right now I'm hoping it's just Disney pumping out different rumours to keep fans of the real story, but in case it does hold truth - I don't understand why.
Han Solo has a certain aura around him that makes you think 'I don't exactly know-know this guy and don't know what he might've been up to in his life' - yet, he doesn't give you the same feel or vibe as Boba Fett, Yoda, Palpatine or Snoke (or Darth Vader when we first saw the movies and didn't found out the truth until Empire) where you can't even make educated guesses and assume certain things.
The fact that they feel Han Solo should be mysterious and that therefore that's not his real name, makes me kind of worried they'll try to make his backstory to epic and big than he deserves; after all, Han Solo to me is as Brax describes him; a tough guy that might have a moral compass that points in the right direction, but who skirts the borders of what's acceptable - and legal - and has a philosophy of looking out for himself.
To me he's the fortune-seeker in the Wild West, a cowboy who wants to make the best of life with the cards he's been dealt and will go to certain lengths to achieve that dream - he is not some sort of mystical John Wick type character with a history as whatever Disney might come up with.
So yeah, conflicted about this one as I feel so far Disney has knocked it outta the park with both TFA and Rogue One and by the looks of the teaser for Last Jedi, is actually trying to bring new depths to the saga, without losing what makes these stories work.
That and the cast just seems brilliantly picked, so I really hope this could be amazing
