Cumberpatch is a brilliant choice as the villian; it makes me excited that he's (very possibly) Gary Mitchell. If true, a big budget version of his story is, for this fan, a 100 times more interesting than seeing Kahn a 3rd time In trek. Why? well, Khan was predictable in his unpredictableness. Gary is just plain scary.
I'll say this: if it was a version of TNG story above, I'd dig it. If memory serves, TNG conveniently decided to forget about that whole arc they created for themselves....or did I forget of a follow up?
