First of all, I think this Kindle edition is cleaned up--there isn't any introduction and there aren't any misplaced pages. Also use of the dictionary is necessary to understand the story.
That said, I'm glad I didn't stop reading when I first became irritated with the writing, because the irritation was intentional on the part of Mr. James. This is a very well-written piece about critics and how they must have irritated Henry James to no end. I read it through a second time to thoroughly understand the main character and how he related to others. It also has me stop to think about writing reviews myself and what biases I might be bringing to what I'm reading. If you take this one on, listen to the narrator's voice and hear how he may sound to his friends and acquaintances, those he criticizes, and how he perceives himself. A worthwhile read.
