I really liked the scenes that showed each Rogue One member sacrifice themselves for the greater good.
I especially liked K-2SO sacrificing himself in the Archive/Data room, to give them enough time to retrieve the plans.
The little nods the movie provided for the fans was a nice touch.
Obviously, the final Vader scene was incredible, and shows how angry, possibly hangry, he can really be.

However, I really hated the CG Tarkin. The scenes with CG Tarkin, threw me out of the movie experience.
Unfortunately, he’s an important character and needed to be in the movie.
It sorta felt like a “Who Framed Roger Rabbit” Meets “Star Wars”, mixing Animation/CG with Live Action.

I’d like to watch it again, since it’s already been a month since I first saw it.
