Hmm, maybe a
little older than me

I didn't see "The Enemy Below" in the theater, but I
did see "Balance of Terror" on its 1st run Dec 15, 1966. Was like 7 years and 3 months old and it was about the most awesome thing I'd ever seen

Still just about my all-time favorite Trek episode (that, and "The Galileo Seven")
To wander even farther OT (gonna get banned here

) speaking of TOS, I was so offended when ST-TNG was announced sometime in 1986 that I refused to watch it for the 1st 2 or 3 seasons. Seemed like blasphemy to me...
Finally I broke down and watched it, and ended up buying all 7 seasons on DVD as soon as each was released - and all 7 seasons of Voyager, and of course all 3 seasons of TOS.
