Is Snoke really Darth Plagueis? He certainly isn't Darth Vader come back from the dead as some misguided theories have suggested. Yes, I agree the musical score is very similar, but perhaps that is because this is the Star Wars genre and they are both Sith Lords.
Is Rey Han's daughter, or Luke's? Was Anikin conceived by Darth Plagueis' willpower? So many weird and wonderful theories to be explored.
They are hours of fun to be had from Googling all the latest in Star Wars chatter. Just today I was checking out a verbal duel between Emo Kylo Ren and Very Lonely Luke on Twitter. I must say that Emo Kylo Ren is hilarious.
Ah well, in the meantime I'll watch The Force Awakens again and patiently wait for the merchandise to catch up with the fans.
