Film noir was once a popular style of films in the United States, and it's easy to see why. With a darkness and deepness that's fairly beautiful in nature and a complexity that is original and hard to replicate, these types of movies (and books) have gone all the way of the world.

Why?

Are people just lazy, or is the beautiful idea of slowly getting linked with some gang or mafia and not finding a way to escape without the threat of death just lost on us these days?

While I don't exactly know these answers to some of these questions, I know that anime came too late for the noir craze. Even so, there are still noir influences on some anime, such as Cowboy Bebop or Monster. Even some parts of Jijoku Shoujo could be considered to have been influenced by film noir.

There is even an anime called Noir, obviously intended to have noir-based roots.

But despite all this, how cool would it be to have an anime completely based on noir, without bringing outside influences? Do you think it would succeed, or do you think we'd chuckle quietly to ourselves at such a preposterous idea?
What do you think?
