“And the Children Shall Lead”
“And the Children Shall Lead” All adult colonists on the planet Triacus have died, but their children do not seem to care much about it. They are under the influence of the “Friendly Angel” Gorgon, the being actually responsible for the deaths. When the children attempt to take over the Enterprise on Gorgon’s order, they can finally be convinced to turn against Gorgon when they learn what he has done to them. summary by Ex-Astris-Scientia
Again considered by many as one of the worst of Trek ever. For me? Well, who am I to disagree? I am a mother but I’ve always hated children (all except my own that is, he’s special 
). It’s also true that Star Trek in general didn’t show chlidren nicely. The Miri, Wesley Crusher, Jake Sisko… ugh…
Anyway, I can understand the kids are easily manipulated. Gorgon can do what he wants but what’s bothering me is why the children could forget their loved ones so promptly. Irritating. Bleh!
