One simply cannot argue with the simplicity of the teaser poster for the latest (8th?) entry in the Alien franchise.
Lots of negative space, the Alien hiding so close in the dark, this could be an image taken directly from the first, and still classic, film. When Ridley Scott went the prequel route with Prometheus, the marketing was very coy about whether or not the film was connected to the franchise, and in this prequel-sequel (second prequel?) they are being as clear as possible. The Xenomorph outside of perhaps Frankenstein, Dracula, and Godzilla, is the one of the most iconic creatures in popular culture, and it certainly makes a lot of sense to maximize its use at this point.
Also, most succinct tagline ever: “Run.”
