Even 30 years later, Alien is still one of the best horror movies ever made.

Rating: 9/10 (11 June 2009)

What can be said about Alien that makes it better than your average horror movie? Well, three things: Suspense, mystery, and atmosphere. Each of those elements work together brilliantly. There's a veil of mystery over every scene, which immerses you in the world and makes you curious about whats going on. The film relies on very taught suspense; sure, you can tell when someones going to be offed by the titular monster, but even then the scenes are directed in a way that makes you hold your breath before the Alien makes its appearance. Just like everything else, even the Alien has a strong veil of mystery. The creature has a complex biology that entices, and the director gives just enough of it to the audience before hiding the rest. A brilliant idea, truly, because it ensures people would go to the sequel, be it good or bad (And in this case, REALLY good, but you already knew that :P). Then there's the way the alien acts. No CG, No animatronics, its a man in the suit, yet its looming presence can be felt throughout the film and believed. This all creates the atmosphere, which is perfect for the film.
The atmosphere of the movie can best be described by the films original tag line: "In space, no one can hear you scream." The film has a lonely, desolate, and hopeless feel, which makes you feel like a member of the ship yourself, dreading the second the feared Alien makes its appearance. Everything is executed so well.
What else can I say, really? If you haven't seen this movie, see it! You've had 30 years to do so, so go out and watch this classic!
