I thought the Tarkin CGI was adequate, but I am surprised they did not do a better job with the coarse looking Leia CGI. Move the camera back or add some smoke. UGH, too fake!
My complaint about TFA was it felt too Disney sanitized for all ages, etc. RO was a bit more gritty, so at least it checks that box, but I have to say that after leaving the theater, I immediately forgot it. Unfortunately, not the best film of 2016 IMHO.
