Reading the thread, I can understand a little better how expectations built up and disappointed some of you a little.
A few observations about topics discussed:
I think one reason lightsabers are given a Mjolnir treatment because of the EU lore of each Jedi carefully crafting this powerful weapon, and because of that only Force users have such an item in their possession. It makes sense to think only Force users can use a lightsaber, but what if we haven't seen "normal" users is because they just never had the opportunity on the big screen?
A big revelation to me about Finn was, I believe, he said the attack on Jakku was his first combat experience. Did Hux or Phasma mention a spotless record for brainwashing, or is it possible there have been other defectors? Adding this with the above... It still seems Finn is Force-sensitive but there are explanatory tidbits out there for him being a normal human.
It seems highly likely Rey keeps it all in the family, but it's also possible some of the recognition in Luke's face is of his old lightsaber, something he thought had been lost to time.
