Fans of the show have hailed this episode as one of their all-time favorites. With its gripping storyline and intense character development, it's no wonder viewers were captivated.

In the Stargate Atlantis episode titled "First Strike (1)", the city of Atlantis finds itself under siege after Earth launches a preemptive attack against a formidable enemy's homeworld. An unstoppable energy weapon brings chaos and excitement as space battles unfold on screen, showcasing the thrilling action that TV does so well.

It's fascinating to see the interconnectedness between different sci-fi series, with callbacks to Firefly evident in both Stargate Atlantis and Stargate SG-1.

One intriguing question that arises from this episode is the peculiar positioning of the city of Atlantis.

Stargate Atlantis - S3E7

#1 - Common Ground (Season 3 - Episode 7)

In the Stargate Atlantis episode "Common Ground," Colonel Sheppard finds himself in a precarious situation. He becomes the prisoner of a Genii commander, but that's not all - he's also trapped with a Wraith who is desperate for sustenance after being separated from his hive. This episode introduces a fascinating character named Todd, who quickly becomes a fan favorite.

One of the reasons why Colonel Sheppard is such a compelling character is his ability to set aside his prejudices when it matters most. He may have his reservations about the Wraith, but he's willing to put them aside in order to survive. Plus, Sheppard has a knack for making friends with just about anyone, even if they're not from his species. It's a testament to the human capacity for forming connections outside of our own kind.

However, not everyone is impressed with the decisions made in this episode. Some viewers believe that Ronon should have been reprimanded for his disrespectful behavior, and that Sheppard's choice to spare Koya was a mistake that now haunts him. Additionally, some fans criticize Weir for making what they perceive as the wrong choice in keeping Ladon in Atlantis, suggesting that she doesn't truly prioritize Sheppard's well-being.

Despite these differing opinions, one thing is for certain - the introduction of the Wraith character adds an interesting dynamic to the show. While some viewers found his story arc to be somewhat predictable, it was still a highly enjoyable aspect of the episode. Plus, viewers are treated to new information about the Wraith, which may have been previously known to some or simply seemed obvious. Overall, "Common Ground" is an episode that leaves viewers on the edge of their seats, eager to see what happens next in the world of Stargate Atlantis.

The episode was rated 8.11 from 576 votes.
