This show has almost a religious significance to me and of course countless others.

Growing up in the 70's, my first TV crush was on Veena (the Cage/Menagerie). The first girl I kissed was a blue-eyed blonde, and later I married a blue-eyed blonde, well, three of them, to be perfectly honest. I think it's Veena's fault. I never did score with a green Orion slave girl, though, despite what they say about them.

While there are many stinker episodes of Star Trek, there are also many masterpieces. "City on the Edge of Forever" is my favorite, for its emotional impact. Who could not fall in love with a young Joan Collins? Another noteworthy episode is "The Doomsday Machine," which is interesting because of its unique musical score, with different instruments/styles for each character. You can find a YouTube video about it, by user shemvonschroeck. I think the most important episode is "Mirror, Mirror", for its (probable) social commentary on American imperialism, the Vietnam War, FBI Director J. Edgar Hoover's spying on members of Congress, and the CIA's use of torture and assassinations in the 60's. We are living in the "Mirror, Mirror" universe. The Utopian Star Trek universe is not our own.

If you like Star Trek, then of course there are the official sequels/spin-offs, but also you should check out Star Trek Continues. And if you like "Mirror, Mirror", then you should check out its Star Trek Continues counterpart, "Fairest of Them All".
