I don't get spoke in the new movie. a friend of mine doesn't get him either, she said he's suppose to be a log (not captain's log, just plain wooden log). but he's having relations... what kind of a log has relations?! plants suppose to wait for bees or wind and they drop seeds in to the ground. they don't even mind if dogs pee on them.
someone who doesn't mind dog peeing on him doesn't have sex!
being a complete nerd and having actually argued this point with several people, it's not that Spock doesn't have emotions, it's that he tries not to show them. He's half human so he does have human emotions, and, despite what they say, Vulcans have emotions too.
I have emotional problems myself, so I can kinda get Spock.
