Stargate: Continuum ( 2008 )
Ba'al travels back in time and prevents the Stargate program from being started. SG-1 must somehow restore history.
That nasty little bugger Ba'al is back and up to his nefarious tricks. Good story, fits in well with the rest of the Stargate franchise and just adds a little bit of tangent to the storyline. Good effects, great cast, interesting and entertaining story and well worth a watch, especially if you are a Gater as you will wallow in this as I did and luxuriate in every minute of it.
