Stargate Atlantis (Seasons 1–5)

Stargate Atlantis (2004) is a science-fiction series you can watch online on iFILM. A spin-off of Stargate SG-1, it sends an international expedition through the gate into the Pegasus Galaxy to find the lost city of the Ancients.

They find the city, and promptly strand themselves there with no way to phone home. Worse, their arrival wakes the Ancients' old enemies: the Wraith, who feed on human life, and later the Replicators. Dr. Elizabeth Weir (Torri Higginson) runs the mission, Major John Sheppard (Joe Flanigan) leads the field teams, scientist Rodney McKay (David Hewlett) snarks his way to a last-second save every other week, and local warrior Teyla and the towering Ronon (Jason Momoa) watch their backs. Each episode means a fresh planet, a fresh threat, another piece of Ancient tech to decode.

Five seasons on the Sci-Fi Channel, running from 2004 to 2009. What sets it apart from the parent show is the isolation: the team is dropped in an unknown galaxy with no backup, which leans the whole series toward exploration and unease. Built for fans of space adventure with real crew chemistry and a dry sense of humor. Stream all seasons of Stargate Atlantis (2004) online on iFILM.
