Nah, I really don’t think anything about TFA made me rethink anything I’d done for my prequel edits at all. If anything, it would reinforce the goal of making the PT conform to the OT somewhat. However, Max Von Sydow made a vague allusion to balance of the force, so I wonder if that doesn’t get brought up again.
And once I saw Snoke onscreen, I thought, “Wow, that really could be Plagueis after all.” I still highly doubt it, but who knows.
I wonder if JJ wanted us to think the planet that got destroyed was Coruscant, or maybe just made it look like Coruscant so that we would take his meaning that he’s ‘destroying’ the prequels.
