Seen the first two movies and lost interested. Never watched a single episode/movie/whatever of Star Trek either.
Star Trek differs from
Star Wars in that most of the things in
Star Trek are actually either very possible(space anomalies, diverse races/worlds) or, in the case of technology, are being developed/researched right now.
I never really watched the first series or movies, but I watch
The Next Generation whenever I see it's on.
