“I can understand this criticism if the characters are meant to be likable, but I see a lot of reviewers rate a book poorly because ‘MC [main character] is a horrible person, and I couldn’t relate to them at all,’ when the character was very clearly intended to be a horrible person. In some of these cases, the horrible traits of said character is the whole point of the book.
Bad people can make good stories, and even prop up a lot of the important themes of the novel. If you have to have a relatable and perfect character to think a book is good, I just can’t trust what you have to say.”
