Alien is one of the most brilliant works of Cinema in history. The special effects still hold up today. Some of the best practical effects I have ever seen. I never to this day think that the effects feel unrealistic due to the time the production took place. They still look incredibly realistic and lived in. The entire ship looks lived in, like its an actual environment. Forgetting the special effects. This film is gorgeously directed and written. The film is so claustrophobic. It never lets you out. It keeps you scared and there is never a moment where you leave your breath in relief. It is intense and scary at the same time. In the first and a bit of the second half. There really is no main protagonist. The entire cast is. You understand who all the characters are and how they work together. Everything has its place, and you understand everything that goes on in an interesting way. Until the scary stuff takes place. You see the main characters step up to take charge. Its absolutely brilliant. Alien is one of my favorite horror movies of all time, and yes horror movies. This movie never gets old, and it still is stronger than most movies today. If you are a fan of horror, PLEASE go check ALIEN out. Its intense, scary , and an absolute thrill ride.
