Review of Stargate: Continuum

The premise of the movie is based on the flawed "grandfather paradox", in that Baal supposedly changed the current timeline by thwarting discovery of the Stargate on earth, causing SG1 never to have existed and Cameron Mitchell never to have been born. The fact that it is meant to have eliminated the current timeline is evidenced by the fact that people and placed resulting from the existence of the Stargate program disappear from the current timeline. In fact, changing past events would have created an alternate timeline without any evidence being apparent in the original timeline and voiding the premise of SG1 rushing to the gate and returning to an unfamiliar timeline. The theory of alternate timelines is that new timelines resulting from alternate versions historical events happening requires that the original timeline continues unnoticed to its inhabitants. That all said, it's still worth seeing for nostalgic purposes of ardent fans, even if the story arc is limited and short sighted.
