I used to when it was on TV a while back. Loved it. Then Stargate Atlantis spin off started and a few episodes had crossover with some from SG1 being in Atlantis but I never continued Atlantis after 1 or 2 Seasons and I don't think I finished the last 1 or 2 Seasons of SG1.
What version of Netflix you have? I'm in Canada and our version if VERY limited compared to the US or Europe version.
I remember being in Europe few years ago being able to watch Simpsons, Rick and Morty.. like literally thousands shows/movies that when I returned to Canada couldn't watch.
Really sucks... apparently. There was a time you could change your ip to US in your browser to fool it into giving you access to more shows but they fixed that .
