I thought the duel was very reminiscent of a Sergio Leone-style gunfight, a huge buildup of tension and then the actual fight is over in a flash. I liked it a lot, it’s really cool to see that kind of sensibility applied to lightsaber dueling.
Also, after scanning comments sections on a few different reviews, I’ve come to the conclusion that there is nothing more tedious in all of Star Wars fandom than discussion of the numbered lightsaber forms.
