So since I plan to run a Dieselpunk community I've been quite busy trying to get a handle on what it means exactly to be a Dieselpunk. Now before you respond, keep reading. Yes I saw the other two threads that discuss this, but I'm taking it a different direction.
What is Dieselpunk that Pulp Noir is not?
One can easily see that "Sin City" both the comic and the movie, is Pulp Noir. But is it also Dieselpunk? One of my friends said no it wasn't, I asked why. He said it was lacking fantastical elements like sentient robots or mad scientists. I countered with Dick Tracy, other than the two-way radio watch it's not much different than Sin City. So is the two-way radio watch the only thing that would make Dick Tracy Dieselpunk? What about before Dieselpunk was coined? It was pulp, it was one of the influences for noir. So it's probably Pulp Noir.
What about Sky Captain? Beyond a doubt an icon of Dieselpunk. And yet, It's film noir. It's a pulp style hero, it's Pulp Noir.
SF Weekly journalist Matt Smith used the term Pulp Noir to describe the act of "Sprinting to the crime scene, skidding on your heels, and yelling at everyone and nobody in particular: 'Who's in charge here?'" To me, that attitude is right at home in Dieselpunk.
Another Observation, most of my friends who identify as being dieselpunk dislike the term and feel it's forced, or gives too much credit to steampunk or cyberpunk.
So I present the question. Aren't we really just fans of Pulp Noir? How is it different than Dieselpunk?
