I am a bit of a sci fi nut. It all started in first grade when they came out with this new channel called the "SciFi Channel." At the time, they didn't have any original programming at the time so they played reruns of older science fiction. I was hooked on Buck Rogers in the 25th Century and Battlestar Galactica.
Then I discovered Star Trek. Glorious Star Trek. I was an instant Trekker. At the time, Next Generation was in about it's 5th or 6th season when I started watching. And when it was finished, I latched onto Voyager. Kinda skipped Deep Space Nine. Then I did Enterprise. It was hard to keep up with it with no cable at college so my Dad taped them and shipped them to me. I also was heavy into the books.
When I was 21, my lifelong dream was fulfilled. I got my picture in the captain's chair.
Then something happened. Gasp. They stopped making Star Trek. Gasp. What to do to fill the void?
I found other stuff.
I had already been watching Stargate SG1 on fox. They had reruns from Showtime on Saturdays.
I tried to get into Atlantis but failed. Until one of my friends in college lent me the first season. Then I was hooked.
One of my other finds was Farscape which I watched on and off. Never got the chance to watch it properly until I bought the DVDs.
I'm a fan of Firefly/Serenity as well but didn't watch it until way after it aired.
Now, I pretty much only read Star Trek New Frontier. It's a novel only series by one of Star Trek's best authors. Reading the most current two right now. Otherwise, it seems that becoming an adult has taken the fun out of sci fi a bit. I don't watch it much anymore.
