Another Neil Gaiman...well not really. I listened to the audio book of Coraline last year. I enjoyed the audio book so much so when I saw the graphic novel, I checked it out. I felt it was a very good depiction of the original book. I think the "Other Mother" in the movie was designed after the "Other Mother" from the graphic novel.
I had imagined the events in the book certain way. So when I watched movie, I was disappointed in a way. The book and the movie are very different. The graphic novel is very true to the book. I enjoyed reading it. I give this book 9/10.
