That was one fun series. Seen most and would watch them again. The one SF series i missed is Star Trek DS9 (and ok the modern version of Battlestar Galactica those human Cylons are scary although the shiny ones with the light look cooler).
And to legitimize this post i will throw in a song. Hawkwinds Spirit of the Age. As song about the impossibility of love when spacefaring (they really don´t do relativity on TV).
I would've liked you to have been deep frozen too
And waiting still as fresh in your flesh for my return to Earth
But your father refused to sign the forms to freeze you
Let's see you'd be about 60 now,
And long dead by the time I return to Earth
My time held dreams were full of you,
As you were when I left;
Still underage
Your android replica is playing up again
Oh, it's no joke
When she comes she moans another's name
The video is time stamped so it starts at 33 seconds. The part before that has some really annoying metallic noises which are not that nice. Never heard them on my casette version.
