So this is the last season of SG:A, and it ends okay. The season storyline never gets fully resolved, but it also doesn’t end on a cliffhanger. In this season, Col. Carter is no longer the head of Atlantis because Amanda Tapping, the actor, went on to do Sanctuary, another Sy-Fy channel show. For dormitos.
Lt. Colonel John Sheppard: Same as always. We also get to see an alternate universe version of him, in which he is not part of the Stargate program.
Teyla Emmagan: Still super awesome. She deals with becoming a new mother and how that her impacts her decision to go on missions.
Ronon Dex: Still awesome punchy man.
Dr. Jennifer Keller: Still awesome. Decides to enter into romantic relationship with Rodney McKay.
Richard Woolsey: Becomes new head of Atlantis. Even though he is an IOA bureaucrat, he comes to appreciate how Atlantis handles problems.
Rodney McKay: Still an asshole, but Dr. Keller manages to instill sense into him.
Dr. Radek Zelenka: Still awesome scientist.
The Wraith: Michael is thought defeated, but shows up in Atlantis to get Teyla’s son. He is defeated thoroughly. Todd has an uneasy truce with Atlantis and attempts to use a newer version of the retrovirus to rid himself of the weakness that is feeding on humans. Also warns Atlantis when he learns that the Wraith know of Earth’s location.
Replicators: So some of the faction that created clones survived, but the clones did not. They become part of subspace and eventually return to Atlantis. Weir has become one of these replicators and helps them regain human form, but also prevents them from becoming a threat.
Favorite episodes: “The Queen” because it shows Teyla being really awesome while pretending to be a Wraith Queen. “Vegas” was the alternate universe episode and it was really cool because it had a Wraith becoming this rock-star type character. I also really liked the song choices for the episode. “First Contact” and “The Lost Tribe” was an awesome two-parter. In it Daniel Jackson comes to Atlantis to search for a hidden laboratory. It is so wonderful because it pits his sarcasm and idealism against McKay’s self-centered arrogance. I really enjoyed that the villains were a lost community of Asgard who wanted to use a weapon to destroy Wraith ships but didn’t care that it also cause every stargate to blow up. Also, having Daniel Jackson in the episodes just increased their quality.
