The plot holes are the least of Disneys issues. There is no character development. No story. Half the movie could have been stripped out and you would never have noticed a difference. Its if they had no plan for the series from the beginning. There isn't even any consistency between 7 and 8. Its like they are writing the story on the fly.
There are so many other issues I haven't even touched. I had to look up what a Mary Sue was the other day. The name Mary Sue fits Rey perfectly. Disney allowed, either the director or the witch from Lucasfilms, political views into the movie. I never thought Disney could take the most beloved franchise and ruin its future in 1 movie. I currently do not count episode 7 & 8 as valid movies in the star wars universe. They are now like the Star Wars Christmas special. Very sad attempts at creativity and are merely a profiting vehicle. Disney will not get another dollar from me!
