With the discovery of a stargate in Antarctica, a new team travels to the Pegasus galaxy to find the lost city of Atlantis and the original builders of the stargates. When they arrive, they’re faced with a technologically advanced enemy, the Wraith.

The concept behind “Stargate” is a fertile one, having spawned two long-running shows. However, in the fourth season, “Atlantis” falters somewhat, hindered by an ever-changing cast.

In this season, Colonel Samantha Carter takes over as the new leader, while the Atlantis crew must team up with the Wraith to fight a common enemy, the Replicators. For sci-fi fans, it’s a worthy franchise to invest in.
