I think the way the book was written just gave me a headache. Examples
"They made Coraline feel uncomfortable. Then Coraline dreamed a few commercials[...]"
"Coraline" and "she" was repeated so much... it made me want to scream.
I feel like this story was told in total monotone. I didn't see any excitement, everything was just flat to me.
I'm sorry, I just didn't enjoy this book. Even though the story was quite interesting, I just couldn't see what all the hype is about.
