Lots of fun, inventive ideas here. I’m especially glad they strayed from dwelling on the old characters, aside from the Falcon, in favor of the next generation (and future of the franchise).
Still wish we knew who that Sith was (my money’s on Adam Driver). He’s probably an Inquisitor (see Star Wars: Rebels), and my theory for that cross-lightsaber is that it’s so powerful, it exhausts extra power. Or it just looks cool.
