History YMMV / StargateSG1

** The Ori arc's catchphrase about "spreading Origin throughout the galaxy" becomes more hilarious with the rise of Creator/ElectronicArts Origin digital download platform as a competitor to UsefulNotes/{{Steam}}. Cue at least one joke about "Hallowed are the EA".

* EvilIsSexy:
** The Goa'uld implicitly invoke this, since they would deliberately take the most beautiful humans they could find as hosts, often resulting in gorgeous men and women leading the evil legions beating on Earth's door.
** Hathor is also likely the patron saint of this trope.
** Adria of the Ori, played by Creator/MorenaBaccarin. Vala makes sure to lampshade how the Ori's (male) followers will probably increase when Adria is full-grown.

** "Proving Ground" has a young Grace Park before she become known to scifi fans for ''Series/BattlestarGalactica2003''.

** "[=Repli-Carter=]" is a human form Replicator created by [[StalkerWithACrush Fifth]] in the image of Samantha Carter and half of the BigBadEnsemble for season 8, along with Anubis. Despite [[BitchInSheepsClothing initially presenting herself]] as an ally to the SGC and [[WoundedGazelleGambit a victim of Fifth's abuse]] while secretly working for Fifth, Repli-Carter soon shows her true colours. [[PlayingBothSides Manipulating Carter and Fifth]] into trusting her, Repli-Carter ultimately betrayed them both, using the former to become immune to an anti-Replicator weapon and killing the latter with no remorse to [[TheStarscream take over the Replicator army]], deriding Fifth as weak and pathetic afterwards. Intending to [[OmnicidalManiac destroy organic life]] and [[TakeOverTheWorld rule the Milky Way]], Repli-Carter leads her army in a genocidal campaign, killing countless innocents. Kidnapping and torturing Daniel Jackson, Repli-Carter tried to force him to give up knowledge of a weapon that could destroy her, planning to destroy it so she could not be stopped. Despite promising to leave Earth alone, Repli-Carter dispatched Replicators to consume the planet, then killed Daniel when she had no more use for him. A [[RoboticPsychopath merciless killing machine]] in the shape of a renowned galactic heroine, Repli-Carter is devoid of the loyalty or morality of the real Carter, making for a coldly ambitious machine hell-bent on galactic domination.

** Senator Kinsey, in the episode he's introduced in, raises some very good points for his decision to shut down the Stargate programme. Namely that the programme is a huge money-sink which frequently risks the safety of the entire planet and generally attracts the attention of hostile aliens with little-to-no returns to speak of (Whatever artifacts the team manage to uncover typically being destroyed), with the team's only argument against him being Daniel's warning of an impeding Goa'uld invasion for which he can offer no evidence to Kingsley beyond his word, which Kingsley understandably doubts. He's only proven wrong after the fact when the Goa'uld do wind up invading and prove capable of reaching earth without the need for a Stargate, thus necessitating the programme's continuation as earth's ''only'' means of striking back.

** Senator Kinsey, in the episode he's introduced in, raises a pretty good point in regards to the Stargate programme being a huge money-sink which introduces far too many risks (attracting the attention of hostile aliens, bringing through elements which could pose a threat to humanity itself, being the only known entry point for the Goa'uld to attack Earth, etc.) with little-to-no returns to speak of. He's eventually proven wrong when the Goa'uld wind up trying to invade Earth via a fleet of ships, thus necessitating the Stargate programme as their ''only'' way of striking back, but it's hard not to agree with his initial views.
** To expand: during the first season, the cast had a bad case of FailureIsTheOnlyOption when it came it acquiring anything useful. Find a device that kills Goa'uld while leaving the host alive? Have to destroy it to save Teal'c. Find an alien database full of useful knowledge? It gets destroyed. Capture a spare Goa'uld human scientists can experiment on? Have to use it to save Teal'c again. Find a handy healing sarcophagus? Yep, destroyed.

* ValuesDissonance: Given how the show starts off in the 1990s, season one in particular does come off as a bit of a time capsule as to how women used to be treated in the military. First off, there's the fact that O'Neill automatically assumes that ''Sam'' must be a guy and there is clear condescension toward her from the rest of the room (leading to the infamous ''reproductive organs on the outside'' line). In a blink and you'll miss it example from "Cold Lazarus", we learn that there is no women's locker room in the SGC - there is a men's locker room that ''becomes'' the women's locker room at various parts of the day. Further demonstrated in the episode "Hathor" where not only are there so few women in Cheyenne Mountain that they can all fit into a single cell and they discuss the fact new personnel arriving are likely to all be men, Carter confesses her worry to Dr Fraiser that the other members of SG-1 think of her as just a girl rather than a fully-fledged comrade. A belief that was perhaps enforced by the fact that when a local woman goes into labour in the episode "Brief Candle", all of the men automatically look to her to be the one to help, even though Carter is neither a medical doctor nor a mother. Needless to say that by the time Carter becomes the commander of Atlantis in the mid-2000s, things have changed dramatically.

** In the pilot episode, O'Neill advises a USAF officer to get himself ressigned to NASA, as "That's where all the action's gonna be. Out there." NASA would go on to become almost a complete non-entity in the series, with the Air Force becoming the de facto spacefaring branch of the government. In seaaon 2, Carter even actively turns down a reassignment to NASA because of how much more action she sees with the Stargate program. In real life NASA has been continually defunded and consigned to robotic exploration whereas the US Military has spent 20 years in wars in Iraq & Afghanistan as well as brushfire actions across the planet.

** Is alternate!President Hank Landry a straight up PresidentEvil or [[OurPresidentsAreDifferent a President Iron]] with a hefty dose of IDidWhatIHadToDo? One hand, he's all but eradicated free speech through state controlled news sources, uses F-302s against anyone on Earth that's deemed a threat, and attempts to imprison Prime!Sam Carter. On the other hand, the universe he inhabits is [[CrapsackWorld far worse off]] than Sam's, something General Hammond is quick to point out. Plus, Sam had accidentally killed her alternate counterpart, depriving Landry of one of his best scientific minds in their war against the Ori.

** "Flesh and Blood" has Creator/JodelleFerland as one of the younger forms of BigBad Adria, years before she starred as Five in ''Series/DarkMatter'', which was created by ''Stargate'' showrunners Joe Mallozzi and Paul Mullie.

* FunnyAneurysmMoment: "2010", an alternate future episode set in that year that aired in 2001, had the characters toasting the memory of General Hammond and talking about how they missed him. Don S. Davis died in 2008. Made even worse because they even state that Hammond supposedly died of a massive heart attack.

* MagnificentBastard: Ba'al. As the only System Lord who seems to remember that the AGodAmI routine is an ''act'', he's far less hammy and arrogant than most Goa'uld, and can sometimes even keep up with SG-1's snark when he wants to. He's pragmatic enough to cooperate with his enemies to deal with greater threats, and unlike most System Lords who prefer to deal with all their problems through overwhelming force, Ba'al is more than willing to utilize unorthodox tactics if they get the job done better. He's also one of the few Goa'uld who we've seen actively pursuing scientific advancement, made all the more impressive since he does so personally rather than delegating like most other System Lords. Between all that and his sheer charisma, you could almost forget he's one of the bad guys, at least until he runs into someone who isn't falling for his smooth talk and he breaks out the torture devices.

** Seasons 5-8: [[BigBad Anubis]] is by far the most evil and dangerous of the Goa'uld [[EvilOverlord System Lords]]. As Selmak said in "[[Recap/StargateSG1S5E16LastStand Last Stand]]", "he was banished by the System Lords because his crimes were unspeakable, [[EvenEvilHasStandards even to the Goa'uld]]"; this is a race of megalomaniacal {{Puppeteer Parasite}}s who think nothing of torturing their dethroned rivals to death, then bringing them back to life and repeatedly doing it again. He tricked Oma Desala, a wise higher-dimensional being, into helping him ascend so that he could become an immortal EnergyBeing, making sure to rub it into her face how she is unable to stop his evil acts. His subsequent plans after his return include repeatedly annihilating civilizations and replacing the Jaffa warriors with mindless super soldiers. After his stable form is destroyed, he starts possessing random people to hold him [[PossessionBurnout until their bodies completely decay after a few days]]. His ultimate plan before he finally got taken out was [[OmnicidalManiac to wipe out all life in the galaxy]] with an Ancient super weapon -- all of it, including his own race and his army -- so he could use the Ancient knowledge he retained to recreate a galaxy's worth of races that would unquestionably [[AGodAmI worship him as a god]].

* CriticalResearchFailure:
** In "Emancipation", the Mongols are portrayed as a society where women were required under pain of death to keep their faces covered and never speak to men in public. This was never the case in Mongol society (instituting such rigid gender segregation would have been wildly impractical for a nomadic people). It's like the writers just said "eh, Mongolia, Saudi Arabia, nobody knows the difference."
** In "Chimera", Carter's love interest suggests a date at the zoo, to which she replies: "There is no zoo in Colorado Springs." There is. The Cheyenne Mountain Zoo was founded in 1926, and became public in 1938. One of the writers tried to HandWave it as Carter being a shut-in, but that seems unlikely given the sheer amount of effort she and the rest of SG-1 went through to acclimate Teal'c to Earth customs. A zoo that is situated on top of the ''same mountain'' as the military base where they work would have been near the top of their to-see list for him. Not to mention, Carter graduated from the Air Force Academy, also in Colorado Springs; the zoo is a common enough attraction for out-of-state cadets with a few days' furlough for Carter to have at least heard about it from her fellow students.
** In "Frozen", the body found in the Antarctic ice is stated to have been frozen for 50 million years. Anarctica was ice-free until about 34 million years ago and didn't become completely frozen until about 16 million years ago.

** In general despite that the NID, Kinsey, Simmons,and reporters are at best proven wrong by the writing and at worst being threats themselves, the SGC has run with a comical level of oversight that would risk disaster were it not for SG-1's plot armor.

** Is alternate!President Hank Landry a straight up PresidentEvil or [[OurPresidentsAreDifferent a President Iron]] with a hefty dose of IDidWhatIHadToDo?

* AuthorsSavingThrow: The first episode basically delivers one to justify the film's claim that Ra was the last of his race; Daniel speculates in the first episode that Ra was just the first of his race to take humans as hosts and others since follow his example. Fanon has also speculated that Ra's previous host was an Asgard to justify its appearance.

* DesignatedVillain: In his first appearance, Senator Kinsey is a little bit of a jerk, but as Chairman of the Senate Appropriations Committee, he's really just doing his job: providing legislative oversight of an executive branch agency. And it's worth noting that the SGC has de facto committed not just the US but all of Earth to an undeclared, secret war against an enemy that at that point in time outguns the Tau'ri by several orders of magnitude, without the informed consent of either Congress or the UN Security Council. SG-1's only real defense is that it's too late and the SGC is needed to defend Earth now, but they have no proof other than Daniel's experience in an AlternateTimeline that any attack is imminent. So ''naturally'', after this episode, Kinsey devolves into a smug {{jerkass}} whose only motivation is the power he'd attain through gaining control of the stargate program.
