  • Here We Go

    O'Neill is about to go on vacation when Thor beams him to his ship. It is over run by little unstoppable techno bugs called replicators. the devour everything in their site and use it to make more of themselves. Can the SG 1 team find a way to destroy the ship before the bugs make it to Earth and destroy humanity.
  • The Replicators debut...

    This was truly an outstanding episode, lots of good action, plenty of humor, and a new really cool enemy. The replicators are favorite enemy throughout the entire series next to the Goa'uld. I just love their theme music, and you get a healthy dose of it here. The music really does a good job of projecting just what a relentless force the Replicators are. While the concept of a technological foe is nothing new(see Borg and Cylons), the way Stargate does it is very innovative. The Replicator are closer to animals than people and unlike the Borg and other technological foes they seek out technology and raw materials rather than seek to obliterate a species, at least until season 6, but we'll get to that in season 6. The only thing lacking in this episode was Daniel, and while that didn't hurt the episode too badly, it does slightly upset the team dynamic. Thankfully, this episode is more about action than anything else. And it has this in spades, plenty of Replicator blasting to keep me happy. This was one heck of a season finale and one that shouldn't be missed. As a matter of fact this was the first episode I saw all the way through, about 7 years ago. Ever since then I was hooked, it is hard to top this show and this episode in my opinion.moreless
  • Another cliffhanger...

    Another season ending - another cliffhanger... It was really exciting episode and.. oh.. I was nailed to the screen all the time, trying to stay calm and not get too excited. The storyline was brilliant - the enemy Asgard were talking about... now it is threatening the Earth. Also, we got the new beginning and it looks like Goa'ulds (even though Aphopis is still not dead) are not so important.

    And the end.. all the things they did on the ship... and then taking the Stargate and getting out.. so good the had one extra... but now they have only one..

    Cannot wait what comes next.moreless
  • In this episode Daniel is recovering from an apendix surgery and the rest of the team is ordered to take a vacation. and Jack is wanting to go fishing and invites sam. But she wants to stay on the base and work on a project that she has been working on.moreless

    As Jack is leaving to go on his trip is suddenly transported to thor's ship. When he gets there he runs into a bunch of machanical spiders. when he finds thor he tells jack that he si sorry for dooming him but they need his help to get rid of the what he called the replicators. But he says there is no way to get off the ship because of the damage they have already done to his ship. So he contacts Hammond via hologram communication. he gives them alist of weapons and explosives he needs to destroy the ship. When Sam offers to help he refuses and makes it an order. But sam and Teal'ccome up with a plan to get them out. So hammond overrides Jack's order and sends them with the supplies. there is alot of shooting and dodging the replicators. They begin to think that thor was right and that they are doomed to die with the ship.

    Thor has become so ill that sam is concerned that he is going to die but he refuses to be put in stasis to save his life until he get back home. Sam decides that the only way to stop the replicators is to place an explosive outside the ship the only way to do this is for Teal'c to go outside the ship and place the explosive. When he is done and tries to return to the safety of the ship the doors will not open, the transport beams cannot reach him because he is to close to the ship so he has to push off so that she can get a lock on him. It takes alot longer than they had hoped, but she finally gets a lock on him and gets him back inside before it is to late. they then transport the stargate onto the ship so they can gate off the ship and then gate back home from somewhere else. But they have to wait till it is just about time to blow the ship to leave through the gate so the replicators dont have time to stop the explosion. Sam brings thor in his pod with her and just as the ship is about to blow they go through the gate. And as the show ends they show the ship entering the atmosphere and it blows up and crashes into the ocean.

    I liked this season finale it was a good cliff hanger. I enjoyed much.moreless
  • A great ending to season 3.

    This episode was great for a number of reasons but the main one has to be that we are introduced to the Replicators for the first time. These little devils show up continuously from this point the main part being season 8. Anyway i was worried that prehaps Thor would not make it but knowing how the Asguard always seem to be ok i'm not too worried. Thsi episode left us with a big cliff hanger is SG1 alive? and now the relicators are on earth. O my god. This show from here on in is simply unmissiable. I am totally hooked. Next season proves to be even greater than this season. The writing is so good.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (4)

    • Trivia: First appearance of the replicators.

    • When Jack is sliding the stone back and forth on the console trying to contact General Hammond, he seems to be pressing too hard on the prop as he leaves scratches on the surface of the console.

    • When Jack is talking to Daniel in the infirmary, the x-ray images on the light board change between shots.

    • If the replicators are attracted by energy pulses from the transporter, how come they miss Tealc's being beamed back on the ship? [Editor's note: Perhaps since they were about to start the descent into Earth's atmosphere, it didn't seem worth it to them.]

  • QUOTES (5)

    • Thor: The Replicators were brought aboard an Asgard ship, for study, before the danger could be fully comprehended.
      Jack: We do that all the time. Kind of expected more from you guys.

    • Jack: Wait a minute. Are you trying to tell me that with all this advanced intergalactic technology, this ship can't withstand a little heat?
      Thor: In order to reflect the subspace field of the phase generators...
      Jack: (interrupts) So... no.

    • Jack: (screams) Come on, come on... breathe! (Teal'c opens eyes) Oh, yeah. That's following orders.

    • Jack: Come on, Teal'c, lighten up. We've been in these situations before...
      Sam: No, sir, we haven't.
      Jack: ...we haven't?

    • Jack: Say something.
      Teal'c: One small step for a Jaffa.
      Jack: Very nice.

  • NOTES (4)

    • From this episode onwards, all the episodes are filmed with 35 mm lenses. Previous episodes were all filmed with 16 mm lenses (except the effect shots).

    • The episode opens with Daniel Jackson confined to the infirmary recovering from an appendectomy. This was written into the script because it actually happened to actor Michael Shanks.

    • For some reason, on the DVD boxed set, the opening credits of this episode are the same as those of the pilot. [Editor's note: Every episode in the season 4 box set has the original opening credits.]

    • Syndication airdate: May 14, 2001.


    • Teal'c: One small step for Jaffa...
      "One small step for man" were the famous words by Neil Armstrong when he first stepped onto the Moon in 1969.

    • Jack: If you don't want to enjoy the beauty of Northern Minnesota...
      This is ironic because Jack "Richard Dean Anderson" is from Minneapolis, Minnesota.
