With six movies spanning for almost 4 decades, the Alien film series is one of the longest-lasting franchises in film history. However, with a lenghty franchise such as this one, you ought to have both ups and downs. Here is the list of the six installments ranked from worst to best by Greatness:
6 . Alien 3
Ellen Ripley (Sigourney Weaver) is the only survivor when she crash lands on Fiorina 161, a bleak wasteland inhabited by former inmates of the planet's maximum security prison. Once again, Ripley must face skepticism and the alien as it hunts down the prisoners and guards. Without weapons or modern technology of any kind, Ripley leads the men into battle against the terrifying creature.
5 . Alien: Resurrection
Two hundred years have passed since Ellen Ripley (Sigourney Weaver) died on Fiorina 161. Aboard the medical research vessel USM Auriga, a team of scientists clone Ripley from her extracted DNA and removes the alien Queen embryo which was growing inside her at the time of her death.
4 . Prometheus
The discovery of a clue to mankind's origins on Earth leads a team of explorers to the darkest parts of the universe. Two brilliant young scientists lead the expedition. Shaw (Noomi Rapace) hopes that they will meet a race of benevolent, godlike beings who will in some way verify her religious beliefs, while Holloway (Logan Marshall-Green) is out to debunk any spiritual notions. However, neither the scientists nor their shipmates are prepared for the unimaginable terrors that await them.
3 . Alien: Covenant
Bound for a remote planet on the far side of the galaxy, members (Katherine Waterston, Billy Crudup) of the colony ship Covenant discover what they think to be an uncharted paradise. While there, they meet David (Michael Fassbender), the synthetic survivor of the doomed Prometheus expedition. The mysterious world soon turns dark and dangerous when a hostile alien life-form forces the crew into a deadly fight for survival.
2 . Alien
In deep space, the crew of the commercial starship Nostromo is awakened from their cryo-sleep capsules halfway through their journey home to investigate a distress call from an alien vessel. The terror begins when the crew encounters a nest of eggs inside the alien ship. An organism from inside an egg leaps out and attaches itself to one of the crew, causing him to fall into a coma.
1 . Aliens
Set in year 2179, 57 years after Alien (1979), Ellen Ripley is rescued by a deep salvage team during her hypersleep. After transmissions from a colony that has since settled on the alien moon suddenly stop (the colony is owned by Weyland-Yutani), Ripley is offered a chance to team up with a group of marines to descend on the moon and investigate the alien presence. A team of colonial marines along with an android named Bishop, Ripley agrees to the offer and prepares to face the alien creature once again. But this time there is more than one Alien.
