My first REAL encounter with Star Trek was movies 3 and 4 over the course of twoo consecutive weeks on Swedish TV in very early nineties. I loved them, and they stuck with me, but they were one offs. There was no other Trek to find.
I first got into Trek for real when TNG started airing in Norway in 1996.
"Encounter at Farpoint" was my first encounter with Trek that got me hooked.
