Re: STAR TREK INTO DARKNESS - Grading & Discussion [SPOILERS]
The Abramsverse is simply playing "what if?" What if Spock's homeworld is destroyed and mother killed? How does that effect a race that is dedicated to logic but has volatile emotions lurking just under the surface?
The Abrams team have done a fine job of it and seem to understand Vulcans in general, and Spock in particular, far better than many "fans".
