...we all went through a Star Trek phase.
I remember someone (Paul? Syme?) years ago telling me they had rented the latest TNG videos and put them on their credit card because they had no money left (eat or watch Star Trek? Eat or watch Star Trek? Hmmm...).
I was watching the original Battlestar Galactica on the Sci Fi Channel, and that was followed by Firefly ('Serenity Pt 2') and that lead straight into the Sunday Night Trek-fest.
TNG was something about Worf's son Alexander coming back from the future to save himself from turning out to be such a wuss. In Voyager, 7 of 9 got multiple personality disorder because of some virus Species 6339 created, then DS9 had an episode where Keiko had been taken over by a wraith who wanted to kill the wormhole aliens and forced O'Brien to sabotage the station to help. Then Enterprise was on - I haven't seen much Enterprise, but honestly, who has? - someone was trying to find out what Reed liked to eat. And then TOS had the infamous "Spock's Brain".
My point is, hands up if you have no idea what I'm talking about.
No one has their hands up, do you?
We all used to watch and even if we haven't seen anything for such a long time, we all know the characters and the situation and thus we could all watch any episode of any show and know immediately what is going on.
