Well, usually in a one man graphic novel, the creator has complete creative control. One characteristic is a unified vision. Since it's all by one person, the art style is consistent throughout. For example, the shading, line work, and color palette all blend together seamlessly. Another aspect is the pacing. The single creator can decide exactly how fast or slow the story unfolds without having to compromise with other contributors. They can also fully explore their own unique themes and ideas without interference.
A 'man graphic novel' could refer to a graphic novel that is mainly targeted at male audiences. It might feature themes, stories, and art styles that are more appealing to men, such as action - packed adventures, superhero stories, or tales of male camaraderie. For example, many superhero graphic novels like those of Batman or Superman have a large male readership.
Well, Future Man is not a graphic novel. It could potentially be a film, a book series, or something else entirely, but definitely not a graphic novel. Maybe you're confusing it with a similar title?
Survival could be a major theme. If there's only one man left, he has to figure out how to stay alive. Another theme might be isolation as he is the last man. And of course, the 'one small step' could suggest the theme of progress or change.
I'm sorry, I haven't read this graphic novel specifically. But generally, a graphic novel combines visual art and storytelling. It might be about the last man in a certain situation taking a small but significant step, perhaps in a post - apocalyptic world or a very isolated scenario.
