Let us not forget that the Enterprise was giving out an annoying subsonic frequency to raise the hackles of the colonists and crewmen down on Omicron as well!

Like some posters!
I know what you mean about not liking this as much when younger but appreciating it more now later in life.
One thing that's very interesting, telling really, is Spock really does have all of these emotions but he's so disciplined that someone that doesn't know him thinks he's emotionless.
The scene when Kirk is calling Spock right after he is infected by the spores is gold, I wouldn't care if the whole rest of the episode was bad (which it isn't) that scene would still stand out.
KIRK : Spock!
SPOCK: Yes, what did you want?
KIRK: Spock, is that you?
SPOCK: Yes, Captain. What did you want?
KIRK: Where are you?
SPOCK: I don't believe I want to tell you.
KIRK: Spock, I don't know what you think you're doing, but this is an order. Report back to me at the settlement in ten minutes. We're evacuating all colonists to Starbase Twenty Seven.
SPOCK: No, I don't think so.
KIRK: You don't think so, what?
SPOCK: I don't think so, sir.
KIRK: Spock, report to me immediately.
KIRK: Spock? Acknowledge.
KIRK: Spock. The frequency is open, but he doesn't answer.
MCCOY: That didn't sound at all like Spock, Jim.
KIRK: No. I thought you said you might like him if he mellowed a little.
MCCOY: I didn't say that.
KIRK: You said that.
MCCOY: Not exactly. He might be in trouble.
Reading it doesn't do it justice, everyone acts and delivers the lines so perfectly, especially the end between Shatner and Kelley.
