* BetterOnDVD: Due to the concept of the film, it is arguably MUCH scarier watching it home alone (preferably at night) than when watching it in a theater.
* HellIsThatNoise: The aliens' speech.
* SpiritualLicensee: With it's CosmicHorrorStory overtones, alien beings that border on EldritchAbomination, use of ApocalypticLog, and [[spoiler: DownerEnding]], this movie manages to really catch the feel of what a Cthulhu Mythos movie would be like when done properly.
