It was a good performance but we need more witty spock than angry spock!
Oh I don't know..
"I intend to assist in the effort to reestablish communication with Starfleet. However, if crew morale is better served by my roaming the halls weeping, I will gladly defer to your medical expertise. Excuse me. "
Yes, credit where its due, that was classic Spock (in fact I wouldn't be surprised if there is a similar scene in TOS
), however by the film's end I get the feeling they are saying: "But we've decided to go another way". In that respect it was a kind of "Spock of two halves" situation.
Never-the-less I think Quinto did as good a job as anyone who isn't (TOS) Nimoy could hope to do from the point of view of his performance. At least when taken separately from what may be happening to the character.
