It’s often daunting to come to a classic film and try to explain why it works so well. Obvious elements spring to mind - the peerless design work, both of the central creature and the sets themselves; the beautifully haunting score; the creation of one of the greatest female action heroes; the perfect pace of the film (slightly spoilt by the Director’s Cut, but the original edit still shines); the “birth” of the creature that may have lost its ability to surprise over time, but still horrifies largely down to the performances that sell this moment so well; the masterful build-up of tension as each character confronts their fate. But, more importantly, this is simply a story that is well told and a reminder of how powerful an experience film can be when all the elements come together so perfectly. Is it any wonder that Alien has been oft-imitated, parodied and copied, but rarely bettered, if at all?
