^^ Yes. Quinto did a good job imitating Spock, although I wasn't that crazy overall with his performance. He was uncannily Spock-like, but I think overall Quinto was just "OK".
Pine didn't "act like Shatner's Kirk", but I think he captured the essence what captain Kirk is supposed to be. People looking for an imitation of TOS Kirk may have been disappointed, but I wasn't.
Urban did the best job of BOTH capturing the essence of the character AND imitating the character.
