Cowboys & Aliens is a testament to how quickly the medium of cinema shifts because this would never be made now. A genre bending blockbuster that's unlike anything else even if it's still based on existing IP. It doesn't entirely cohere and is way more self serious than you'd expect this concept to be but the collision of a western and science fiction keeps it entertaining.
Daniel Craig was born to play a man with no name. The strong silent type is a natural fit for him and considering the overly serious tone, his performance makes for the ideal lead. As a gruff rancher with a heart of gold, Harrison Ford is also playing squarely to his strengths and Olivia Wilde does her best with the weakest character who the script completely mishandled.
Jon Favreau's direction struggles with the logistics of staging action involving cowboys, aliens and spaceships but he's really good at using the cinematic language of the western. In that first half hour, the film commits wholeheartedly to being a stereotypical western which makes the hard pivot into sci-fi (and a pretty nasty one at that) all the more effective.
