Honestly, I don't like Mike's idea for a 7th movie because, ironically, his idea lines up with part of what made the prequels stink - over explaining things. Do we really need an explanation on how Luke's trainees/academy came to be or why (going off of his idea) the Republic decided to build a Super Death Star? (Let alone why suddenly the Rebellion decided making a Death Star was a good thing). I honestly don't even care about how The First Order came to be, in fact I don't even think they needed an explanation or a new name - just keep calling them The Empire. The only interesting part of his idea was the story of how Kylo Ren fell to the dark side, however that story would ruin part of what made Kylo so interesting in the Episode 7 we got.
I've noticed in a lot of his videos that Mike frequent proposes over-explaining things and has issues when things are not explained in great detail even though that's not realistic at all. It's actually a big writer's no-no to overexplain things but nerds constantly plead for it because that's what they're spending their evenings obsessing over.
I'm a nerd too, I love all those details. The entire reason I loved the book Bloodline was because it was a nerdgasm of backstory. They don't need the movie to be that way, though. It slows things down and leaves nothing to the imagination. The unexplained gets the imagination running, makes the world feel bigger, and leaves you craving more. Later when some explanations start trickling in you are much more satisfied.
I expect some of those answers will start rolling in a little more once Luke starts talking. If they didn't I'd be disappointed. However I also expect them to hold some back because overexplaining kills imagination dead.
I still cant wrap my head around the fact that he hates ID4 because he didn't know exactly where the aliens came from and exactly what their step by step plan was. That's entirely missing the point. He loved ID4-2, though, because that fucking mess overexplained every minute detail that nobody wanted to hear. Even Jay couldn't fathom what Mike was on about in that video.
