So that being said, I'll go first. I am a serious sci-fi nerd. Star Wars (the movies, never cared for the books), Star Trek (TOS, TNG, DS9, didn't watch VOY or ENG). But if you want really good sci-fi, you have to read. Heinlein, Asimov, Clarke, Gibson, Dick. I've read a lot of the first three, and have a lot of the last two on my to read list. If you like the political intrigue aspect of BSG, I strongly recommend "The Moon is a Harsh Mistress" by Heinlein. That's all I can remember off the top of my head.
What about all of you?
EDIT: How could I forget B5 and Farscape? ::hangs head in shame:: Both were great series, loved them.
