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.
There's a huge difference between a smart science fiction movie and an actual course in science.
Since we were talking about 'Cowboys and Aliens' in Weird Westerns I figured anyone on the thread would realize that that by 'smart' I meant a movie dealing with interesting ideas and not just a big shoot-'em-up.
I feel sorry for anyone who treats entertainment as an examination. And, since you cite numerous problems, I'll assume you were silly enough to torture yourself by watching the whole thing.
I think the problem is that you called it smart.
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."
