Balance of Terror - okay so it's a WWII warship vs. submarine movie, but the performance from the Romulan commander (Mark Lenard, who would go on to play Spock's father in later episodes) and the whole cat-and-mouse scenario combined to make a truly unforgettable episode.

The Doomsday Machine - an extremely dramatic episode with a fantastic performance by William Windom as Commodore Decker make this another unforgettable one for me.

There are a bunch of other standout ep's but those are my two favorites.

I like the one where the spaceships go 'pew! pew!'

I can't think of any off hand that I would consider a favourite, though I am a very casual fan of the series. 


That said I read a Star Trek novel that my folks had at home once that was pretty interesting, about some planet which had Devil-like aliens in it and it was pretty interesting and introduced me to Sci-fi novels [it was the first 'set in space' book I read when I was very young.]

I can't remember the exact plot, but I remember one of the aliens seducing someone with their 'devil' ways and something about the lead alien possibly being a vegan [or at least having a particular diet of some sort]

Very hazy, yes, but I remember enjoying it all the same.

Tough question. I've been watching TOS again for the first time in a few years, and I keep getting reminded of great episodes.

I would have to put The Doomsday Machine high on the list. Not only a great performance by William Windom, but I always thought the planet killer itself was a really cool machine.

Spock's Brain is good. Kind of a funny episode with some neat ideas, and Deforest Kelley is at his scenery-chewing best.

The City on the Edge of Forever has lots going for it. A solid time-travel story with humour, drama and lots of insane Bones.

And the funniest episodes, A Piece of the Action and The Trouble with Tribbles both have a lot going for them.

Also, A Wolf in the Fold, That Which Remains, The Squire of Gothos, By Any Other Name, The Naked Time and certainly more.

I haven't watched TOS in a long time, I should get on that again. I remember some years ago, a friend had borrowed me his DVDs, and I was really surprised at how good this one episode was. I had expected the show to be much more campy...which, I guess, some episodes will deliver. Anyway, in said episode, Kirk lands on some planet, loses his memory, and becomes part of what I remember as being an indian tribe. Anyone know the name of that ep?

[AndyC]

That was The Paradise Syndrome.

[Ed, Ego and Superego]

TOS- Balance of Terror
TNG- Inner Light- where Picard lives a whole life as someone else in a few minutes.
DS9- The Die is Cast- Where the Cardassiana nd Romulans attack the Dominon, and get stepped on.
Voyager- two of them
  Equinox- Where Voyager discovers a ship who didn't take teh high road to get home.
  Basics I/II- The Season 2 fanale where the crewman who murdered is required to save the ship.
Enterprise- Never got into it (I blame the theme song) But I did like the role the Andorians played (Jeffry Combs!)
