I have this friend of mine who was interested in Star Trek but didn't feel like watching TOS because of his undeniable aging (it was a low budget 60s tv show after all) so I rewatched almost every episode to make a list of the unmissable ones. I've condensed the serie and I presented him this list 1x10 The corbomite maneveur (I've chose this as the starting point don't hate me) 1x05 The enemy within 1x06 Mudd's Women (because the heavy sexism here makes me laugh genuinely) 1x13 The coscience of the king 1x14 Balance of terror 1x18 Arena (because of the best sci-fi battle ever) 1x22 Space Seed 1x25 The Devil in the Dark 1x28 City on the edge of forever 2x01 Amok Time 2x04 Mirror Mirror 2x06 The doomsday machine 2x10 journey to Babel 2x15 the trouble with tribbles 3x07 Day of the dove 3x09 the tholian web 3x23 all our yesterdays All our yesterday was included just because "turnabout intruder" is one of the worst episodes of TOS imho and as a season ending it sucks so much that before "These are the voyages..." I had nothing to compare this episode to. What do you guys think about this list? Would you add something? if so, why?
