The most fun I've had watching this film. Splendid and truly a masterful edit. Other reviewers have already noted the stellar editing—audio and video—and I can only concur. The original is not fresh in my mind but if you did the handful of match cuts, then bravo!
This feels like a "Star Wars: An Event"-film set in the SW-universe, where I don't have to wonder why someone has godlike aim for a blind person. Clearly he's one with the force, and therefore it's explained why he dodges and fires like a master. Rogue One: The Battle of Scarif is pretty much a perfect standalone movie within the Saga, easily replacing the original.
I loved this edit. It felt fun, and like a "Star Wars Short" or something, which is what i was looking for for Rogue One. The theatrical versions seems to force the need to be as important as the other Star Wars films, but it just isn't. This movie cut to the chase without trying to create a reason there was a weak spot on the Death Star. Instead, it just focuses on the rogue team sacrificing their lives to get the plans to the Death Star. Short and sweet. No need for deep character development. Just a quick fun ride, which is what Star Wars should be IMO - fun.
As a fan of Rogue One I was pretty interested to watch this edit, knowing it basically just the big ending battle presented as a short film. But, I think the editor did a really great job making it seem like more than just the battle. The opening crawl is great, as is how it leads into the opening scene of this edit. The editing is seamless and there were a few parts that if I didn't know there should have been something there I wouldn't have noticed. The editor did an awesome job putting this together. The audio is pretty nice too, and all the music selections seemed to fit the scenes nicely. There were a few times the music seemed a bit louder than the dialogue, but it wasn't off putting or anything.
All in all, I'm very impressed with the edit and I'm really glad I got the opportunity to watch it.
