There are a lot of qualities that make The Thing work so well as a horror film. It has been rightly lauded for its set-piece moments and striking practical effects, but what keeps this timeless are the same elements that can be found in a similar classic film of the time, Ridley Scott's Alien - the beautiful yet harsh outdoor locations photographed to stunning effect, creating a sense of scale and isolation that remind the viewer how cut-off the characters are and contrasting sharply with the claustrophobic interiors ; the minimalist score from Morricone that adds to the tension ; the great production design that ensure the setting feels like a realistic working environment ; the memorable characters, notably of course Kurt Russell's Macready ; the efficient script that introduces the personalities of the main group quickly and the camaraderie between the characters that ensure the audience believe in the group as a working community and care about their survival. But this is no mere retread of another film - the alien presence here working from within to split the group apart rather than bringing them together. Unlike Alien, the central villain is harder to define and from the opening moments, Carpenter creates a sense of unease and paranoia that permeates the whole film right through to the final frame, ensuring the audience like the characters themselves are never quite sure who to trust. The effects may have dated to a modern audience (though the tangible feel to the practical work is creepier than anything that could be created in CGI) but it's the quieter set-piece moments of tension and mistrust that remain just as strong as ever and make this Carpenter's best film.
