Some fans will disagree with this choice, but I find Ethan Peck’s portrayal of a younger Spock to be as close as Nimoy might have been if he had portrayed a younger version of himself. Peck emulates the rage Nimoy had to play into in “Amok Time,” and he has had to conquer difficult situations that Nimoy was never put into, which gives him the unique opportunity to bring out different sides of Spock. He is still learning as this Spock and will eventually become the more logical-minded Vulcan.
Playing a human trying to play a Vulcan was a challenge that Peck pulled off quite well, even down to the weird smiles that he was unaccustomed to. He is a not yet in full control of his emotions so it stands to reason that he would not be in the original Spock’s caliber yet. He’s growing and still dealing with his human side which is why he fell into love with Nurse Chapel. I would not be surprised if that becomes one of the defining moments that makes Spock become more like the unemotional Vulcan we see on Captain Kirk’s Enteprise. Overall, though, Peck is my second favorite Vulcan.
