Having just watched the series finale of Stargate SG-1 a few hours ago, I have a request for science fiction show writers: please do not write any more finales that involve the use of time travel. The paradoxes and inconsistencies you inevitable create make my head hurt and distract from the warm fuzzy feelings I would like to have at your accomplishment. I first discovered this phenomenon with the finale of Star Trek: The Next Generation, and rediscovered it when SG-1 used a time travel story to wrap up Richard Dean Anderson’s run on the show two years ago. And tonight wasn’t any better.
Oh man, I just remembered, one of the SG-1 DVD movies is an alternate reality story. I better stock up on the Excedrin now.
