There was a great quote in one of the reviews I read that said we, as a society, used to go to movies to wonder about the future (and the OT certainly fits that bill). Now we seem to be in love with reliving the past.
Back in the 70’s the movies were great, now they’re complete uninspired crap. I love the fact that Rogue One has some really great nostalgia to it while at the same time being different.
