Just went to see it last night. It was ok.
I get that they wanted to have Vader in it, but he sounded like a 70-year old version and it's impossible to have Vader without David Prowse. At least TRY to mimic his movements.
I can't believe that anyone wouldn't realize that Tarkin was cgi. I liked the effort, but they should have kept it minimal and not shown him so much or so closely so as to easily see that it was cgi.
Came home and watched Episode IV and while I appreciate the effort of tying in the ending of Rogue One, it sort of screws up the tracking of spies, etc. to the Princess and the "diplomatic mission" of her ship.
