My random thoughts...
I think Rey is Luke's daughter and Finn is his son. Finn said he was separated from his parents when he was very young and became a Storm Trooper. Rey "has" the force and is an outstanding pilot (like Luke and Anakin). The lightsaber 'called' to her.
What is the time period supposed to be between Return of the Jedi and Force Awakens? While the main characters obviously aged, it doesn't seem immensely so. I figure Ren is in his early 20's.
Why would R2D2 go into "low power mode" when Luke left and pick this exact time to "revive"?
No one could go into a droid's memory?
How does a PART of an map become "missing"? R2D2 has all the map, presumably showing the path of Luke (the red line?) except the final part, but he was in "low power mode" since Luke left.
The First Order had the part of the map that R2 had in his memory banks. Where did they get it?
The First Order came about how? They obviously "took over" the storm troopers, but wasn't the Death Star(s) the central communication points?
The Falcon fires right up after how many YEARS of it sitting neglected? And hitting all the stuff on Jakku didn't affect it's flying ability?
I know a lot of people liked the "familiar", but I thought there was too much familiar... trench runs (two in this movie), the 'bar' with strange creatures, a whiny character trying to control the force, etc.
I was entertained, but it wasn't my favorite. I really wasn't happy with story. The acting and special effects I liked.
