I think this bringing back characters/actors in digital form isn't quite there yet. Grand Moff Tarkin in Rogue One was almost comic book like, Carrie Fisher as Leia in the later Star Wars films was almost there, as was Rachael in Blade Runner 2049. but imho Its always the eyes that aren't quite right. (even when they are not green
)
I also think, you are so focused on the digital re-creation, perhaps searching for faults, you sometimes miss whats happening in the scene itself. I guess there will be a time when the technology is so good, we will no longer focus on it so much.
ie I remember watching 'The Thing' prequel, and although I generally enjoyed it, the CGI monster was so (for best of word)... 'bland', it totally lost the vibe of the original for me, resulting in me focusing on it throughout the whole film, which ultimately left a bad taste.
