PS has Barbara Babcock, ATCSL has Melvin Belli.
PS has Michael Dunn, ATCSL has those kids.
PS has one of the most clear and striking demonstrations of Gene's vision (before he listened too much to his own hype and age and abuse caught up to him) of a better future for Humankind while still showing idle power is corrupting.
ALEXANDER: You know, I believe you are. Listen, where you come from, are there a lot of people without the power and my size?
KIRK: Alexander, where I come from, size, shape, or color makes no difference, and nobody has the power.
PS also have some excellent scenes of Spock dealing with his emotions.
KIRK: Can you do anything for him?
MCCOY: There is no medicine that can help him. He'll have to come through this himself.
SPOCK: I trust they did not injure you too much, Captain.
KIRK: My muscles are sore, that's all.
SPOCK: The humiliation must have been most difficult for you to bear. I can understand.
MCCOY: The release of emotions, Mister Spock, is what keeps us healthy. Emotionally healthy, that is.
SPOCK: That may be, Doctor. However, I have noted that the healthy release of emotion is frequently very unhealthy for those closest to you.
KIRK: Which just goes to prove that there's no such thing as a perfect solution.
SPOCK: So it would seem. Captain.
KIRK: Yes, Spock.
SPOCK: Do you still feel anger toward Parmen?
KIRK: Great anger.
SPOCK: And you, Doctor?
MCCOY: Yes, Spock. And hatred.
SPOCK: Then you must release it, gentlemen, as I must master mine. I might have seriously injured you, Captain, even killed you. They have evoked such great hatred in me, I cannot allow it to go further. I must master it. I must control.
And Kirk with Alexander
ALEXANDER: He's right. I should have warned you. They were treating you the same way they treat me. Just like me, only you fight them. All the time, I thought it was me, my mind that couldn't move a pebble. They even told I was lucky they bothered keep me around at all, and I believed them. The arms and legs of everybody's whim. Look down, don't meet their eyes. Smile. Smile. These great people, they were gods to me. But you showed me what they really are. And now I know, don't you see. It's not me, it's not my size, it's them! It's them! It's them!
(Alexander breaks an urn and takes a sharp shard of pottery.)
KIRK: Put it down.
ALEXANDER: No. This is the best thing for them.
KIRK: Put it down. Do what I say.
ALEXANDER: I'm going to cut their I'm going to cut them. Parmen first, and they'll all get infected. But this time, listen, whatever they say, don't save them. Let them die.
KIRK: Give it to me!
ALEXANDER: At least let me give them a taste of what they gave me. Please, they're going to kill you anyway. You know that.
KIRK: In that case, what's the point in you dying too, Alexander? Give it to me.
ALEXANDER: That's the first time anybody ever thought of my life before his own. I should have told you when you first came here that they were going to kill you. Because I knew, but I was afraid. I was afraid.
KIRK: That's all right. It's all right, Alexander. Listen, we haven't given up, and there may be something you can do to help.
ATCSL has kids pretending to be bees and eating wobble.
