ST original series inspired many generations, including mine. I literally grew up with ST, remembering watching it as a little guy back in 68, but falling in love with it as a kid in reruns during the 70s. One of the first times in my life where I felt old, was when I saw the original Enterprise model in the Smithsonian.
@Brittney - Recent offerings of Sci-Fi worth watching; Firefly and the 2003-2007 Battlestar Galactica series. I would add Heroes, but the last two years of that series really stunk it up.
