In the Stargate Atlantis episode "The Last Man (1)", Sheppard returns to the city after a mission, only to find it completely abandoned. The once bustling Atlantis is now eerily quiet, with all systems dead. But that's not all - instead of the familiar ocean, Sheppard is met with vast sand dunes stretching as far as the eye can see. The mystery deepens as he tries to unravel what has happened to the city and its inhabitants.

Fans of Stargate Atlantis will be delighted to see Colonel Carter making her appearance in this episode. Although her screen time in this season is lower than expected, her presence adds an exciting dynamic to the story. Another familiar face that might catch your attention is Robert Picardo, who dons a red uniform in this episode. A small detail, but for fans of Star Trek: Voyager, it's a fun nod.

"The Last Man (1)" is an exceptional "clip show" in Stargate history. Unlike traditional clip shows that rely on old footage, this episode presents new material in the form of vignettes tied together with low-budget scenes. The storytelling style is engaging, although some fans may have preferred a different ending, with Sheppard going into stasis and leaving the rest for the next season.

Delightfully dark and reminiscent of post-apocalyptic stories like "On The Beach," this episode captivates viewers with its apocalyptic atmosphere. However, some fans felt that the season 4 finale, including this episode, was a bit of a letdown. With multiple storylines involving wraith, replicators, and Michael, it seemed like the season lacked direction. Despite this, "The Last Man (1)" is still a thrilling and thought-provoking episode that will leave fans wanting more.

It seems like the show is taking a turn, and viewers can expect to see more of Amanda Tapping in the remaining episodes. However, some fans have raised an interesting point about her wardrobe choice - why is she wearing a leather jacket instead of her usual USAF uniform while on duty?

With intriguing plot developments and the promise of a thrilling alliance, this episode of Stargate Atlantis is sure to keep viewers on the edge of their seats.

In the Stargate Atlantis episode "Midway," Teal'c pays a visit to Atlantis to offer guidance to the headstrong Ronon, who is facing a review by the I.O.A. However, their plans take an unexpected turn when the Wraith launch an invasion on the Midway space station, with Earth as their ultimate target. As the Wraith threat looms, Teal'c and Ronon must put aside their differences and join forces to protect their home.

Fans of the show may find Ronon's initial hostility towards Teal'c a bit surprising. In fact, some viewers feel that it is out of character for him to display such animosity before understanding the purpose of Teal'c's presence in Atlantis. Perhaps it would have made more sense if Ronon had been open-minded or even neutral towards Teal'c until the true reason for his visit was revealed - as Ronon's "interview coach" for the IOA evaluations. Nonetheless, despite this minor inconsistency, the episode delivers plenty of adrenaline-pumping action and maintains an exceptional pace.

While "Midway" may not be the most captivating storyline in Stargate Atlantis, it compensates with its thrilling action sequences. The episode keeps viewers on the edge of their seats as the Wraith invasion poses a grave threat to Earth. With Teal'c and Ronon forced to work together, the episode promises an exciting display of teamwork and bravery. So, buckle up and get ready for a rollercoaster ride of adventure in "Midway."
