I agree. I think a seething, intense, boiling Spock is much more scary and emotional than just seeing him burst out like any old "human".
There's nothing like that seething anger Spock shows in ST6 when he bats the phaser out of Valeris's hand. You see that deep, profound anger coming from the depths of his soul, just peeking out, and it is way more intense and frightening than a shouting match would have been. Ditto when he shows that bit of pain after his mind meld and he says with a slight break in his voice, "She does not know."
And you wouldn't believe the idiots that were calling that rape.
Mind rape.
But the look in her eyes said she totally wanted it.
