What movies do you think have given off the right feeling of atmosphere that they were supposed to be set in? Alien does a great job feeling confined and building tension as you feel like you're on the ship with the characters. Aliens does okay at it too, especially the scenes in the ductwork, and I Am Legend did a great job of giving off the feeling of an empty world but the tension and sense of danger is lacking for some reason to me. Omega Man did a good job of both giving off a sense of danger and the emptiness. Let's hear your picks. Aside from the creatures in I Am Legend and Omega Man I find those worlds really inviting. You know there are other survivors but you don't have to worry about tripping over them all the time. EDIT: Changed it to list your unsuccessful atmospheres.
