Boy Sparkie, you hit the nacelle on the head with THE OMEGA GLORY, the single most addlepated piece of detritus to grace a cathode ray tube. And what's particularly tragic is that it was one of Gene Roddenberry's original handful of 'gems' that he took from door to door hat in hand as he tried to launch what became STAR TREK. It might be interesting to trace the various script permutations that de-volved into the nonsensical messterpiece that we have today. But as it stands, I'm afraid that E Pleb Neesta can't Plegli Unum to THE OMEGA GLORY.

As to THE LIGHTS OF ZETAR, it's redeemed for me by the understated tragedy of our beloved Scotty having to put his one and only girlfriend on tumble dry. Let us reserve a special purgatory for the 'girl friend' episodes, flat as they may fall.

Except for James Tomcat Kirk, who has more girlfriend episodes than even the Captain's Log can keep track of. And speaking of which, didn't Shari Lewis have something to do with that episode (title escapes me, which speaks for itself) where Kirk and his date are marooned on a fake Enterprise built to befuddle him on some overpopulated planet? This episode too might rise to the top of the puddle if not for the drek that is THE OMEGA STINKBOMB.

Now about the best of TOS, tough choice. THE CITY ON THE EDGE OF FOREVER naturally comes to mind as a given, but mostly because it's so untypical. So as an example of the best of 'Classic Trek', the one that contains the most exemplary elements of the show as a whole, I nominate THE IMMUNITY SYNDROME (the one with the big amoeba).

I'm afraid that I can't speak with any sort of authority about subsequent pretender series, so I'll just note that the Next Generation episode ALL GOOD THINGS was so good that it overshadowed ALL subsequent theatrical derivations of that series.
"Good night, Dr. Carruthers." "Goood - Bye, Roy................."
