I saw the movie a few days ago and have been trying to read through this thread before posting my thoughts. I didn't make, and I might never make it, so here goes anyways.
1. Thought it was awesome. Can't say I'm surprised that there are people that are being hipsters about it in this thread, because that is what we are now as a culture. But for what it is - a fun space fantasy - it was fantastic. I keep seeing it being placed on par with ROTJ, and I think I would probably slot it in there just ahead and solidly in third place for me.
2. I did not realize there would be a discussion about whether Rey is the progeny of one of the main characters from the OT. She is the daughter of Luke or Leia (but not both you sick weirdos floating that idea). I get that based on what we know now that you can say "but why did this thing happen then....?" but I learned something about good writing from watching Breaking Bad and more importantly listening to podcasts about it where supposed experts kept trying to predict where it was going and thinking the writers were locked into certain plot progressions based on the way they presented something previously, and every time the writers would write their way around and make it make total sense in retrospect. I think there is too much to suggest that Rey is a Skywalker descendant at this point, and nothing the writers have done so far really eliminates that from being the case.
3. Speaking of writing. I've seen a couple mentions of JJ Abrams and what he will do with the next films in the part of this thread I read. Maybe it was corrected later on, but JJ is done with the series. Rian Johnson is writing/directing Episode 8 and I believe he is now signed on for Episode 9, as well. Rian Johnson did Looper, which I thought was very good and very smart, and I'm not generally a science fiction nerd movie type.
I'm going to keep reading this thread and if I ever finish it I might chime in with more. (Maybe I can get through it faster if I ignore the endless discussion about parsecs as a distance vs. time measurement.)
