This is an interesting move for comic books in the 80's. The hero is very introspective, and a lot of panel time is spent on character development over action. The total destruction of the "other self" or the "secret identity" helps to push this farther from a superhero book. The aesthetic is similar to a horror comic, and it has a preponderance of green with splashes of other colors. 
 The best story was the one with the Monkey King. A monster that embodies fear and is going after children is a solid model. This would have been the same time Stephen King was working on IT, so I wonder what was in the water or the pop culture that hit Moore and King at the same time.
