I thought Sam and John Doe were just the pre-bastardized versions of Finn and Poe in the final movie. John helps Sam (a former Stormtrooper) defect from the Neo Empire the same way Poe helps Finn leave the Fail Order in TFA. IIRC Sam was never confirmed to be a Solo child, just a Han Solo-esque character as far as I know.
For all I know, you could be right about John Doe just being folded into Poe, but given how his ethnicity and character personality didn't carry over to Poe, who knows.
I've read multiple times that Sam was in fact supposed to be a Solo. Apparently a big part of his character was going to be him having an inferiority complex with being Han Solo's son, and having to live up to the namesake. He was even
stylized to have visual similarities to Han in all of his concept art appearances with Kira.
But whether he retained his Solo lineage or not, his planned character trajectory about
falling to the Dark Side under Darth Talon's hold, and Kira spending the trilogy desperately trying to pull him back, sounds infinitely better than what we got.
This is me 100%. Growing up Luke was never my favorite SW character. But after watching the OT for the first time in years before TFA came out I really started to appreciate his character and his arc of turning into a Jedi. That's why the sequels feel like such a slap in the face. Luke was a mcguffin in TFA with one entire scene and no dialogue, then he was such an unbearable asshole in TLJ, and by TROS I couldn't care less.
You don't know what you've got till it's gone. As a kid, I always used to pass over characters like Luke because to my insecure, pre-formed mind, traits like altruism and pure-heartedness were uncool and lame, and nowhere as alluring as all the edgy anti-hero types in fiction.
But as time has gone on, I've really gravitated more towards those "boy scout" characters in fiction, like Luke Skywalker, Steve Rogers, Clark Kent and even King Arthur. Good men struggling to be better than they can be, to treat the world better than the world's treated them. To be that kind of person, and not become jaded and cynical like so many of us would be when faced with the same obstacles, is what make these kinds of characters admirable, and refreshing.
And that's what makes Luke's adventures in the EU so rewarding, because you can see Luke use these traits to help and inspire people around him. The day he's forced to depart into a shameful, forced exile by the government in FOTJ, and he's at the temple gates to disembark, there's a horde of characters--Jedi and non-Jedi alike--swarming him, teary-eyed, because they can't repay all the ways he's helped them. How he pulled all of them from a dark place, taught them and united them all together. One even character tells him: "Look around, Master Skywalker.
This is your legacy." It's why in spite of all the ST's desperate attempts to "deconstruct" Luke, they failed to understand why a new Jedi Order led by him would be such a big deal, and a grand departure from the Jedi of old.
Because even the thankless authors writing the EU recognized that Luke's greatest accomplishment wasn't being the leading force of a New Jedi Order, but being its heart. That's why the books, despite lacking the money and star-power of the new films, feel like a truer continuation of his journey.
