The attention to detail and continuity was impressive. Vader's suit in Rogue One is exactly the same as it is in A New Hope, and this movie ends right before A New Hope begins. Seeing the dynamic between Vader and Tarkin and Tarkin and Krennic was awesome, and seeing the life of the man responsible for the Death Star, tying up what was arguably the biggest loose end in the Star Wars franchise; the exhaust port vulnerability, was fantastic!
