In the series finale, the Atlantis team is contacted by none other than their old friend Todd the Wraith, who tells them an underling has marooned him on a planet and taken over the Wraith hive ship. As if that weren't bad enough, the hive ship is now powered by a ZPM and the super-energy source is transforming the craft into an invincible weapon. While those on Atlantis try to destroy the ship, it jumps to hyperspace and has a very clear destination in mind: Earth. Sheppard is recalled home to man their best defense while Teyla, Ronon and McKay find themselves battling the Wraith from within their ship. In the end, Atlantis must travel to Earth for the final battle. Written by garykmcd

Did You Know?


The Swedish airing of the series finale was planned to follow the previous weeks episode as scheduled, on its normal time-slot at Friday 9pm February 6th 2009, but got canceled during the preceding days, due to the fact that the tapes had not been delivered from USA on time. The finale never aired during the following week's regular time-slot, but instead premiered as a finale of the first completed rerun of the show, on Tuesday February 24th 2009, during the weekday's rerun time-slot 5pm. This outraged many viewers, some of whom didn't follow the reruns and knew it would air at all during that time-slot, but instead waited for the premiere during the channel's normal 'Friday Sci-Fi' time-slot, and of those who knew of the premiere during the rerun time-slot, many had no chance of watching it that early in the evening. Nevertheless, the finale ended up getting more viewers than what was normal for both the normal Friday night time-slot, and the weekdays afternoon re-run time-slot. See more »

Absolute and Utter Madness
7 September 2015 | by XweAponXSee all my reviews

I actually missed the last 3 seasons of Atlantis, so a slight binge-watch was required for me to catch up.

This episode ties in to the previous "alternate-timeline" episode "Vegas" (which was filmed in Vegas) where we got to meet another alternate version of John Sheppard, one who was very much like his Wraith Buddy "Todd": i.e., half crazy. Originally I assumed that the Mackay alternate in that episode was the same one that rode Mackay's "Bridge" and caused yet another ZPM to be prematurely depleted. But that Mackay had stated that his "Sheppard" was even smarter than he was, a Mensa type. This parallels Sheppard to Jack O'Neil who while feigning simplicity or ignorance, was actually very smart.

Something very bad from that alternate episode finds it's way into our Atlantis 'verse, but it happens while the Daedalus is trying to deal with a Hive Ship that is being powered by a ZPM! Of course, our friend Todd the Wraith had brought Atlantis this information. and of course, he has left out many important things.

This episode starts like all the rest of the Season-5 episodes, but it escalates from five minutes in. By sheer luck, the Daedalus is not vaporized by the ZPM-powered Hive, but that same ill luck brings that bad thing from the alternate universe into our 'verse.

Surprisingly, this episode features that last ever appearance of "Kavanaugh" (Ben Cotton) and he saves the day, just like he did when he suggested blowing the back hatch of the Puddle Jumper in the Season 1 episode that introduced the Iratus Bugs. So, after 5 years of being assigned butt-jobs on Midway Station and on the Daedalus, Kavanaugh finally becomes a hero- If he had not been actually doing his job, it never would have happened.

But from then on, it becomes a race to Earth. Who will get their first, the ZPM'd Hive ship or... Well, Both Oddysey Class ships are in the Milky way, so what ship can be used to get to Earth? Also, when Atlantis tries to open the Gate to Earth, it does not quite connect. But where is it going? Or are they too late and the Wraith are already bombarding Homeworld Command?

Meanwhile, Sheppard had gated to Earth because he was supposed to be using the Antarctic Weapons Platform, the only problem is due to stupidity, it was moved. So he has to man an X-302, and once again he has to bring it right into a Hive Ship.

From all angles, it looks like a suicide mission, for everyone. But the shark jumps in just the right way to make this an unexpected ending of a great show.

I had hoped that Atlantis were to be given at least two Movies or Miniseries like SG-1 had been given, but the promised "Stargate: Extinction" never happened, unless you count a comic book version.

Regardless of how these shows ended, there is still much more story to tell. And more "Even Worse" bad guys waiting out there.

This is why I like the Stargate Universe (Including the show of that name), it may not be as cool as the Star Trek universe, but there are plenty of interesting things out there, many of them dangerous, but many of them very cool. Which is why I hope these franchises will one day be re-ignited.
