I LOVE ST classic, I do. But sometimes things happen within an episode that just make you go: ''WTF?''
I was re-watching THE CITY ON THE EDGE OF FOREVER recently, the part soon after McCoy has fled down to the Gateway planet. Now McCoy is out of his mind from a chemical 'overdose' and naturally Kirk is beaming down to the planet to rescue him. The planet is of unknown risk at this point.
So Kirk leads a landing party to the surface- of course Kirk would be there, he's the boss plus Bones is his good friend. He brings Spock along, good idea you need a science officer to analyze whatever unknown thing could be there.
There's two security guards, they might be useful to restrain McCoy if he becomes violent, or if there's some dangerous beastie to zap into nothingness.
And then we have...the Chief engineer and the head of communications?!?
I really fail to see how their specific skills would have been useful for a rescue mission on an almost-deserted planet.
Yes I know, they are the main actors and they were needed to say the lines assigned to the crewmen that had to stay behind, but forgetting all that one has to wonder what's up with Kirk? No wonder the M-5 gave him such a hard time if he makes such bizarre command decisions...
He didn't bring another doctor or even a nurse along...
What the hell, Kirk?
