Point is: Spock has never been played 100% emotionless.
No one said he should be.
Quinto's Spock is pretty on course for what we've seen in the past from Nimoy.
Quinto plays Spock as a super passive-aggressive human being. Okay, the script is responsible for a lot of that, but I'm sure Quinto could underplay it a bit so that it's not so over the top.
And I won't even bring up "KHAAAAAAAAAAAAAAAAAAAAAAAAAAAN!!!!" (Mostly, though, because I don't want you to counter with "THE WOMEN!!!")
