19. The Thing (1982)
Directed by veteran horror movie director, John Carpenter, an expedition of scientists to the Antarctica promptly gets unpleasant as they find out that a shape-shifting alien that takes the appearance of the creature it kills is after them.
It’s one of the best classic sci fi horror movies ever and takes full advantage of the snowy environment it is in, which helped build up tension in the air and an all-around sense of danger throughout.
18. Videodrome (1983)
A disreputable TV-Programmer acquires a new type of programming for his station, which leads his life and the future of media to go bonkers.
Though the horror parts of the film are done well but it does end up feeling a bit stale in terms of how the characters interacted with one another.
17. The Mist (2007)
An unpredictable storm hits a town and unleashes a weird species of monsters. Thus, a small group of people are held up in a supermarket to fend for their lives.
The real point of the film is to show what extremes even the most normal of people will take when their lives are at stake. Despite of the fact that the film features one of the most tragic endings in cinematic history, it’s still one of the most enjoyable sci fi alien movies ever.
16. 28 Weeks Later (2007)
28 weeks after the rage virus had infested in the population of Great Britain, the US army steps in to salvage a few survivors in a small section of London, in order to repopulate and start again.
However, things don’t exactly go according to plan. It promises to be one of the greatest horror movie sequels ever put to film.
15. Slither (2006)
A small town is infested with humans turned to mutant-like zombie creatures, due to some alien plague overtaking the place.
14. The Brood (1979)
A psychologist uses some unorthodox therapy techniques on his patients thus violating their brains. Thereafter, the husband of one of those victims is trying to uncover the truth, and this is somehow connected to a series of murders.
A very exhilarating murder mystery psychology thriller with some deep horror elements included.
13. Tremors (1990)
Locals of a small and mostly barren town are forced to defend themselves against weird worm-like creatures that live underground.
The horror in the film really comes from the vigorous environment as the creatures could literally come out from anywhere. It’s a really fun to watch film with a great science fiction plot.
12. Cloverfield (2008)
This found footage movie is basically Godzilla, but in the form of horror, as we literally only see the humans perspective of the monsters attack on the city through the found footage.
One thing this film does well is its usage of the monster as its face is never shown until the end and is mostly never onscreen to help build up its presence. It definitely stands amongst the best found footage movies of all time.
11. Scanners (1981)
A scientist turns a scanner, a person who has unbelievable psychic powers, to his side and sends him to kill other scanners like him to put a stop the underground movement of all the scanners.
It’s more action than horror but still well executed for the most part.
