My first Stargate SG-1 episode
21 January 2021 | by ashil-john-See all my reviews

This was the very first Stargate SG-1 episode I ever saw; it was an early morning rerun. Needless to say, I was instantly hooked, and went on to binge watch the entire series. It remains to this day one of my favorite TV shows of all-time.

A very memorable episode.
