A redditer gives his list of the 20 essential Trek episodes:
ENT: In A Mirror, Darkly, Dear Doctor, Carbon Creek
TOS: City on the Edge of Forever, Balance of Terror, Space Seed, Mirror Mirror, The Trouble With Tribbles
TNG: Q Who, The Best of Both Worlds, The Defector, Yesterday's Enterprise, The Inner Light, Tapestry, Preemptive Strike
DS9: Duet, The Visitor, In the Pale Moonlight
VOY: Scorpion
Commenters put forth missing episodes like Far Beyond the Stars, Cause and Effect, Year of Hell, Drumhead, Measure of a Man, etc.
I'm going to omit my commentary for now, but what do you guys think? Do some of these fit more in the category of "popular" or "got a lot of exposure" than "essential"?
