It's Alien, the 8th passenger.

Rating: 10/10 (8 September 2006)

Alien is a genius blend of science fiction and horror. As a matter of fact, it doesn't get much better than this. The plot is rather smart for a science fiction or horror movie, which adds to the realism of an other-worldly creature stalking our characters through the spaceship.
The creature effects and design are mind blowing and I'll never ever be able to figure out how creativity was so well used here. This movie, along with Aliens, serves as the godfather of modern fright. The scares are well crafted and performed and Sigorney Weaver is just excellent.
I highly suggest this movie to Horror Buffs, no matter what age. It's so wort the view, that it's impossible to hate this movie.
