Okay, since so many of us thought that last TV show list sucked, I Googled for a list of Sci-Fi genre shows, and found this one on Wikipedia here
http://en.wikipedia.org/wiki/List_of_science_fiction_television_programs So the instructions go:
BOLD if you have seen ALL EPISODES
ITALICS if you have seen AT LEAST ONE
Some of these shows are older than I am...and I'm about the oldest person among my flisters...so don't worry if you've never heard of it. In fact, you can put a strikethrough for shows you've never heard of if you want. And I'm going to leave it as it to start and put my own in a comment, so you have a clean list to copy. Isn't that nice of me?
