But don't you think that a young Spock learning to control his emotions could be an interesting plot point in this film?My only real fear about the reboot is that they're going to give some major character or other key element of the Star Trek universe a bit too radical a departure from its original characteristics. It only takes one such "rogue" element to stick out like a sore thumb and detract from the rest of the movie big time. The trailers depicting an emotional Spock send up more red flags than a May Day parade in Beijing.
I agree that I don't want to see an "overly emotional" Spock in this film, but I think that one of the story lines this film will explore will be how Spock learned to control his emotions, even when being provoked (as Pine's Kirk was obviously doing in the trailer).
Young Spock can get emotional -- e.g. he broadly smiles at blue plants that make chiming noises, he gets angry when provoked by Pine's Kirk, and he frenziedly yells "THE WOMEN" when Colt and Number One disappear off the transpoter pad. Older TOS Spock has learned to control those emotions.
This is true, but I think the fear of an overemotional Spock is real, too. In this area, what I fear is a Spock that is reckless and illogical because of his emotions. For instance, we'll have to wait to see the context of the situation, but I'll be disappointed if he left his command with the entire planet of Vulcan in jeopardy only to see to his parents and the Vulcan elite. What about the needs of the many...?
To be sure, we've seen a greater range of behavior in Vulcan characters on Trek since Spock. And that makes sense. They can't all be Spock. But compared to those Vulcans, overall there was something taciturn about Spock. His demeanor conveyed an inherent dignity and even pride. The Vulcan's Vulcan. Not that he always had to have it, but it might be hard to see him without it. I just hope they didn't go overboard with his "inner struggle."
