cause they're damn near there with the pixels...i could have squinted and tarkin probably wouldn't have been in the uncanny valley.

it's just that the muscle movements are a bit off. the other cgi character near the end they pulled off almost perfectly

and honestly, i have more of an issue with vader's speaking voice during his first scene. it just didn't have the aura of original trilogy vader. but boy did they bring it home the next time he showed up. that shit was intense.
