i felt it might've been better if they just used makeup, prosthetics, and camera angles to make guy henry look more like peter cushing for tarkin.
henry already looks like a cushing a bit too.
the same for the actress who played leia at the end.
the cgi was good, way better than tron legacy now, but still has something off about it - so the uncanny valley effect took me out of the movie a little bit.
still, i thought the movie was great. it's probably within my top 3 star wars movies now.
