The ads for the DVD and Blu-Ray releases are right in labeling it “the movie experience of a generation.”
Absolutely. If Episodes VIII and IX are anywhere near as good people will see TFA as the rebirth of the franchise.
Honestly a lot of that is going to ride on Rogue One and Han Solo as well. If those aren’t at least good, then people will start to be a bit less enthusiastic about Lucasfilms new direction.
