YMMV: Aliens

  • Base Breaker: Newt. She's either The Scrappy (to the point where the fandom supports the third film for killing her off) or she's The Woobie.
  • Better on DVD: The extended cut restores Newt's backstory, where her father was the first colonist who was infected, and Ripley's subplot of her heartbreak over losing her daughter during hypersleep, thereby adding a much deeper dimension to her relationship with Newt. These additions do interfere with the film's pacing, however; it's up to the individual viewer's opinion as to whether or not the trade-off is worth it.
  • Broken Base: This movie is either considered to be a worthy followup to the original or the inferior to the original, but critically it is considered better than anything after it. This is especially prominent on IMDB, where the user reviews range from the majority of very positive to the Vocal Minority of outright hate.
  • Discredited Meme: Carrie Henn, who played Newt, has said that she hates the line "They mostly come at night. Mostly." Possibly because people spin it into the worst pickup line ever.
  • Ensemble Darkhorse:
    • Hudson, having so many memorable lines.
    • Bishop, to the point that he's basically the second main character of the Alien franchise after Ripley.
    • Vasquez as well thanks to Jeanette Goldstein's iconic performance, to the point that she got a trope named after her.
  • Even Better Sequel: While the original Alien is a great movie - interesting characters, creepy and horrifying designs for the alien, it introduced the xenomorph life cycle to an unsuspecting populace, and so on - the second movie is widely (though not universally) regarded as a better film. It also benefited from a Genre Shift from straight up Horror to Action Horror, which meant that instead of suffering from Sequelitis, Aliens was able to do things its own way.
  • Genre Turning Point:
    • In American futuristic SF, the role of women was changed forever because of this film. Afterward, there was no room for any Neutral Female or Damsel in Distress in the future for any major female character; now they are expected to grab a weapon and join the fighting as much as any man.
    • This was also the movie that made it stylish to have your future soldiers use high-tech kinetic firearms instead of "ray guns".
  • Hilarious in Hindsight: Vasquez asks Ferro about Ripley "Who's Snow White?" Ten years later Sigourney Weaver plays Snow White's stepmother in Snow White: A Tale of Terror. The line was also meant to use Snow White as a metaphor for 'weak female'. Then comes Snow White's Xenafication in the film Snow White & the Huntsman and the TV show Once Upon a Time.
  • Idiot Plot: A couple of examples by the Marines:
    • They were overconfident and failed to set up appropriate backup plans before being stranded on LV-426. Justified in that Burke was pulling strings to place an inexperienced lieutenant in command that he could boss around and wanted someone to get infected so he could sneak Alien embryos back to Earth.
    • Why a massive spaceship is sent out with two dropships and for some reason nobody stays behind (is there no Navy in charge of running the ship?), not even a second platoon in case of emergency, is never explained. Maybe that's Burke manipulations again?
  • Memetic Mutation:
    • The phrase, "Nuke the site from orbit. It's the only way to be sure," is often used. A minor alteration is to simply tag "It's the only way to be sure" to any drastic suggestion.
    • Imitating Hudson's line, "Game over, man! Game over!" Or just about anything Hudson says really.
    • Keeping something handy "for close encounters."
    • "Stay Frosty"
    • "They mostly come at night. Mostly."
    • "Get away from her, you bitch!" along with the concept of the Power Loader/Alien Queen fight.
    • Bishop's knife trick predates this film by hundreds of years, but is likely only well-known today as a result of it.
    • Honestly, it would be easier to just call this movie a massive Fountain of Memes and be done with it. Almost every line of dialogue, every story beat, and every character name has entered pop culture.
  • Moral Event Horizon: Burke locking Ripley and Newt in a soundproof room with two facehuggers so he can smuggle the alien embryos back to Earth.
  • Most Annoying Sound: Fans who dislike Newt usually point to her extremely, almost inhumanly high-pitched squeal, which sounds more like a tailpipe whistle than a screaming child.
  • Most Wonderful Sound / Hell Is That Noise: Fans love the high pitched shrieks and squeals the aliens make so much that there was outrage that it wasn't included in Aliens: Colonial Marines, even though they have been the preferred vocalisations used in all previous Aliens videogames.
    • The same goes with the sounds the Pulse Rifles and Smartguns make when they fire.
  • Nightmare Fuel: There's a whole page dedicated to this.
  • Sci Fi Ghetto. Averted. Sigourney Weaver received an Academy Award nomination for Best Actress as Ripley.
  • Sequelitis: The film avoided this by using a completely different genre. While Alien was more horror/suspense, Aliens was a pretty straightforward sci-fi action film with a few moments of suspense/horror. Everything after the first two movies tries to copy one of those two formulas.
  • Special Effect Failure: Towards the end of the movie, when "torn-in-half" Bishop stretches to stop Newt from being sucked out an airlock, the hole in the floor he's actually standing in and his lower body are clearly visible. This was fixed in the Blu-Ray release of the film.
    • More of an editing failure, but prior to the Blu-ray release there's a scene where Ripley takes a Pulse Rifle and Flamethrower off the rack and tapes them together over 4 shots. The failure is in the weapons swapping when she places them down. (She grabs a flamethrower and puts down a rifle, then vice versa).
    • The dropship suffers from some very obvious green screen matting at some points.
    • When Ripley and Newt are trapped with the facehuggers and Newt tells Ripley to break the glass of the window, the "glass" rebounds from the chair just like plastic.
  • Spiritual Licensee: Halo takes a great deal of inspiration from Aliens, including the space marines, the flying dropships, kinetic weapons, battles with parasitic aliens, and Sergeant Johnson, who is basically just Apone with a different name.
    • Aliens itself is often referred to as a stealth adaptation of Robert A. Heinlein's Starship Troopers — and a far superior adaptation to the later officially-licensed film. And even though it was just one suit, Aliens even had more Powered Armor than the actual Starship Troopers film franchise (at least until the third, straight-to-DVD film).
  • Suspiciously Similar Song: Because of the incredible time pressure that James Horner was under when he composed the Aliens score, he borrows from his own Klingon theme from Star Trek III: The Search for Spock, as well as Khachaturian's Gayane Adagio.
  • Values Dissonance: Spankings and smoking are ay-okay in this movie; although the cigarettes are said to be "de-nicotined" according to the novelization.
  • Vindicated by Cable: The film was very popular on its first run, but didn't achieve the legendary status it has in pop culture until after it hit video.
  • Visual Effects of Awesome:
    • The Alien Queen designed by Stan Winston helped him win his first Special Effects Oscar. The same goes with the other Power Loader that fought it, which caused many companies to demand a real-life one.
    • The same goes with the Xenomorphs. Only a few full suits were built and yet every trick in the book was used to give the illusion of multiple aliens fighting the marines.
  • What an Idiot:
    • Dropship pilot and gunner leave the loading ramp open and unguarded during their stand-by. They may have wanted to save time and fuel by landing close by instead of returning to ship or staying in the air but open ramp puts this into Too Dumb to Live territory.
    • Ripley and Burke for not speaking up to explain to the Marines why they had to switch from pulse rifles to flame throwers. Well, that might have been Burke following his own agenda, but it's less justified with Ripley.
  • What Do You Mean, It's Not Political?: Inverted. The film has some intentional parallels to the Vietnam War according to James Cameron.
  • The Woobie: Newt. She's been orphaned and traumatized by an alien attack and continues to be antagonized by the monsters throughout the movie. To make things worse, the happy ending with Ripley is undone by her death in the third.
