Another nitpick I have is how odd it feels for Leia to have had a lightsaber, but chose to leave it with Luke all this time, and his Force ghost leads Rey to it so there can be two sabers in the finale without one having a red blade.

I would have preferred Rey to have started building her own saber earlier on as part of her training. Kylo could have still gotten the Graflex saber from Rey in the same manner, then we could see her use the saber she’d been working on for the first time.

Still, just another nitpick and as I said above, I continue to enjoy the movie very much.
