Finally managed to watch Rogue One on DVD. (I have a Lucas canon die-hard sibling; it's very difficult to even mention Disney era stuff in her presence...) It's less derivative than The Force Awakens, opening up the universe beyond the Skywalker clan (which, really, is one of the Force's great galactic mistakes, all things considered), though it took a bit for me to get into the story; heavy accents didn't help. The FX were very impressive, and the sets had more of a Star Wars feel than some of FA did (though, once again, it was missing the Lucas-era critters in the corners to make the alien worlds really seem alive.) The ending, while it added weight to A New Hope's victory, was rather a gut-slug/downer; I'm not sure how people subjected themselves to that multiple times in theaters, TBH... On the down side, I found some of the tie-ins and callbacks to the original movie a little heavy-handed... and, especially after seeing The Expanse, much of the cast outside the main crew looked awfully white and male. I'm also not sure how well it would stand up on its own - if nothing else, it'd be rather bleak if one didn't know where things went from here. (On the plus side, we're guaranteed this one won't be a trilogy...)
I'd call it good-to-very-good, though for some reason I'd been expecting very-good-to-great.
Might have a different opinion on rewatch. The Lucas-loving relative got wind that I'd rented it, and has decided she might want to see it... will probably get to that Monday or Tuesday. Eh, well - it's a cheap per-night rate...
