That particular scene was quite gripping to me and I thought DeForest Kelley did an outstanding job with it. (Much better, by the way, than the Spock scene that followed -- how could that be one of Spock's painful memories? He was just born?
Uhh...it wasn't about him being a baby.
true, and the point of the scene was a good one, as was Spock's response to Sybok.
but it is ridiculous that Sybok could be pulling that scene out of Spock's memories, unless it's just supposed to be something he constructed out of his imagination.
