YMMV / Species

  • Alternate Character Interpretation: The alien species that sent the message with the information to create Sil. Was it all an evil plan to exterminate the human population over the Earth and replace it with Sil's offspring as it looks, or it was a genuinely friendly attempt to share biotechnology that got screwed because Finch and company couldn't handle it the right way?
  • Best Known for the Fanservice: The Species films are mainly known for one thing: Natasha Hensridge taking her clothes off a lot. Or her equivalents in the third and fourth movies.
  • Evil Is Sexy: Downright enforced, as the deadly alien hybrids look like supermodels in their human forms.
  • Foe Yay: One-sided; due to Sil and Eve's natural instinct to mate, they seem to develop a minor attraction to Preston. However Preston sees them both as a monster that has to be destroyed.
  • Hilarious in Hindsight: One of Sil's victims in the first was named John F. Carey. The 2004 Presidential candidate was John F. Kerry, who was a well-known senator at the time of the movie.
  • Nightmare Fuel: Many of the deaths are brutal (such as Sil ripping the spine of a woman), the alien transformations are as disgusting as the ones from Alien, and even the first movie's soundtrack contributes to a creepy atmosphere, while maintaining a sense of innocence and naievete that makes Sil such a relatable (and thus, all the more horrifying) villain.
  • Paranoia Fuel: See Fan Disservice.
  • Retroactive Recognition: Michelle Williams as the young Sil.
  • Sequelitis: The third and fourth films came about by the two-picture deal with Syfy. The third pretty much comes off more like you would expect a scifi TV show to. Which to some was a far cry from the first two, while others appreciated it. While the director of the third had plans for the fourth, it instead tried to examine a different What Happened to the Mouse? and most would probably agree made a film that made the second and third less bothersome.
  • Special Effect Failure:
    • The aliens' prosthetics in Species III are vastly inferior to what was seen in the two previous films. The Awakening has similarly bad effects, but for the most part it does a better job of working around them.
    • In the first film, the "mist" in the woods outside the hot tub guy's house is patchy, obviously from a smoke machine. Also the Conspicuous CGI in the final scenes (which H.R. Giger complained about, saying that unlike the animatronics they weren't worthy translations of his design).
  • Strawman Has a Point: Dr. Xavier Fitch says they made the alien female because they assumed she'd be more docile, which is seen as funny by Preston and it's actually untrue as female members in Earthly predatory species tend to be more aggressive than males (it's mostly mammals who buck the trend). But by doing so they actually may have bought themselves more time, considering a female only can have one partner and reproduce more or less one by one while a male can have multiple ones at once and impregnate all of them. And considering what we see of the clearly more dangerous male hybrid in the first sequel, he turns out to be pretty close to being entirely accurate. Basically, Right for the Wrong Reasons.
