Not to derail the thread, but I’d like to share my opinion on the whole lightsaber thing.
I agree with Rian’s sentiments, in theory. Lightsabers aren’t as mythically important as JJ made them out to be, and destroying the Skywalker saber was a great choice that symbolized the whole “letting go of the past” theme. I just don’t like how Rian went the complete opposite direction, treating the saber like a joke. With Luke throwing it over his shoulder, the CGI puffins playing with it, and Luke calling it a “laser sword” later on, it feels like an important element of Star Wars being treated like trash. Lightsabers aren’t sacred, but they aren’t a joke either.
But I do wish that Rey used her own saber in TROS. By far the best part of Trevorrow’s discarded script was Rey building a double bladed lightsaber out of her staff. Combine that idea with the yellow blade shown at the end of TROS, and you would have a wonderful, unconventional weapon for Rey to wield in the final movie.
