To be fair, I think the first half of this movie is great. There are a lot of long, slow shots which really feel reminiscent of a spaghetti western. But as it goes on, it eventually just turns into a mindless action movie with lots of quick cuts and as much CGI as they can fit on the screen. So yet another entry into the "yes, this movie is bad, but it's a Weird Western!" category.
Weird West (or Weird Western) is a genre of fiction that uses the Wild West period of American History as a foundation and then adds fantasy/supernatural elements to it. So stories where gunslingers encounter zombies, vampires, demons, robots, or any other creatures that wouldn't otherwise be present in a standard Western.
This is a community for sharing various Weird West works. Movies, Books, Comics, Video Games, TV Shows, whatever fits.
Like I said; if we're talking about 'Cowboys And Aliens' in the Weird Western section, we've already given up on scientific accuracy as a metric.
If you want a highly researched and peer reviewed analysis of the physics of a popular icon, I refer you to Larry Niven's seminal work, "Man of Steel, Woman of Kleenex."
