this kind of reminds me of the Matrix:Reloaded in some ways when "The Architect" gave people tons of things to think about and argue about....and since that is the case, I want to wait until Ep.9 to make final judgment as we're not in the final episode of the story yet. Things can change. Maybe Kylo is telling lies to Rey, maybe Snoke is Dark Plageus and isn't dead yet.
What if Luke is not entirely right about the Jedi/Force? The appearance of Yoda and his IMO completely perfect reaction was great. Will Rey and others create a new thing that isn't the Jedi but better? And where are the other people who left with Kylo Ren? Someone suggested that they were the red guards around Snoke but I don't think so
