I vaguely remember watching parts of TOS with my dad as a 6-year-old just before I went to bed. He was the one that really got me into it, though I don't really remember a whole lot about what drew me in, but I did like "The guy with the pointy ears". I can also remember renting the movies and sitting as a family in the living room with giant bowls of popcorn while we enjoyed the flick.
