Jon Cole writes: Serial science fiction television shows are a dime a dozen. Of course, the quintessential series that pops into most people's minds is Star Trek, whether in its original form or its many variants. The list goes on, including titles like Babylon 5, Sliders, Lost, The X-Files, V, Quantum Leap, The Outer Limits... I've made my point. Few manage to survive past several seasons, with most losing too many primary actors to be viable, retreading the same ground too many times, or simply just not retaining the spark that made them popular in the first place. One true survivor managed to catch my attention recently, lasting an entire ten seasons and holding the mantle as longest-running sci-fi series for quite some time. That television show is, of course, Stargate SG-1.
