As a person that voted Five Stars myself, I voted because I see no problems with the book. The idea that perfection is elusive or doesn’t exist has always annoyed me, and the idea that a really good score has to be subjective and based entirely on emotion is equally problematic.
I can break down why I would give maximum marks to a #1. This is a shortened list because some things only apply to certain books.
On the art side I consider anything worth that mark if it displays a unified and fluid reading experience with a clear visual narrative. That requires crafted composition and a sense of visual punctuation, as well as a consistent style and approach to the subject. It can be a style I am not keen on, it can flow in challenging ways, but as long as it is consistent with the story and enhances the overall message then I can’t mark down the art.
On the story side there has to be evidence of craft. Specifically a starting issue’s job is to intrigue and draw us in. It has to create a situation and a setting and make us want to know what is going to happen next. The action needs to flow and be well paced, the points need to be delivered clearly. This includes new characters being fleshed out enough to get an insight into them and be intriguing and old characters being either recognisable and engaged in something intriguing or slightly off in ways that themselves intrigue. Any world building or exposition should be sprinkled throughout in a natural way, ideally as indirect exposition unless there is a good reason or excuse to do otherwise. Direct exposition should be easy to read and not take up undue space or attention, and it should tie back into what we are reading and enhance the story.
Now I could just go through that list and explain why this book meets those criteria, but this is where subjective elements come in. Subjectivity need not be based on intangibles like emotional reaction or notions of perfection. If one is rigorous and structured in ones critique they can go hand in hand. Subjective reactions within an objective framework.
In a nutshell this book subjectivity satisfied me in many ways that can be objectively teased out and appraised. (I couldn’t resist the Claremontian nod.)
I would like to think this kind of rigour is more common than it appears. That even if subconscious we have a number of objective questions we each ask of the text.
