Stargate SG-1: Every Season Ranked Worst To Best

Season 7 was the undoubtable peak of the show, where we had our initial line-up of the cast together for the last time.

Daniel Jackson, after his attempted interference in Anubis' plot at the end of Season 6, was cast down from the ranks of Ascended beings with his memory in tatters, then to be found by SG-1. As he begins to remember his past life, Anubis moves to threaten the home world of Jonas Quinn, hastening the departure of Daniel's eager replacement, although we would see him one more time this season.

While there are the standard few fun episodes this season - like Space Race and Fragile Balance - the majority of this season was given over to the rapidly rising threat of Anubis himself. As the most powerful Goa'uld that the SGC had ever faced, he posed a threat to the entire galaxy and would eventually set his sights on Earth. Before that, he would develop his Kull Warriors, his super soldiers whose black carapace armour and near invulnerability is the worst nightmare the SGC could have faced at this crucial time.

Episodes like Lifeboat and Orpheus would show the struggle and hardships of team members like Daniel and Teal'c, but nothing would come close to hammering that point home than the two-part episode Heroes.

Finally, Anubis brings his forces to bear on Earth, mere weeks after a new President has taken office and been briefed on the threat. As behind the scenes forces threaten to destabilise the SGC, SG-1 have to depart on a dangerous mission to find a lost city of the Ancients, pursued by the entire fleet of Anubis. Their only hope is speed, luck and the backup of a ship called Prometheus.

This was intended to be the final season of SG-1, and there are only a few details added in at the last minute to have changed that. Initially, Atlantis was meant to have been discovered on Earth, but the decision was made to move it to another galaxy at the last moment. So while this season had all the intensity of a final season of a show, it was simply its best instead.
