I think it's a good thing that the last SW I had watched was Episode III; this was my first teaser of the Disney era, and what can I say: I will not watch this one, just as I did not watched the others.
(For me, the Star Wars franchise is Star Wars from 1977, and I don't care about the other films or television series.)
Yes. The duel with Vader is the best moment of the films imo. Not flashy, but full of meaning and innuendo.
