Yeah it seems that he's taken some artistic licence there with Spock, but it's weird to have Leonard Nimoy's voice come out of him! Also only a couple of the likenesses are ok (Kirk and McCoy), but that's fine - they match the characters if not the actors - the facial expressions are greatly done. Sulu though look like he's recovering form a skin disease of sorts close up - that's my only real criticism.
i like it's not in the same style as the Animated Series, but rather something different and new.
Yo can tell especially with Spock and Uhura, that the actors recorded their lines around TUC, but that's OK, it's easy to just enjoy another adventure with Kirk, Spock etc. The gang back together.
