It's possible that we might be able to work our way OUT of the uncanny valley, once the technology becomes good enough. It isn't 'more realistic is creepy' it's that once you skirt towards realistic, you have to get it closer and closer to humans to avoid creepy. At which point, you have to ask yourself, why not just cast human beings?

Tintin is still Uncanny Valley, IMO. Getting closer, but still no cigar.
