picking a book out

Today I was thinking why don't a book have interest or what make it interesting
and what is the most important skill to have? so I was thinking in the past that most people in my class chose predicting more then wow moment. And this shock me because I was wondering why would my classmate use more predicting then wow moment as a skill to there reading. I think that people read more predicting skill in reading because it is easy for them to use predicting as a skill then using wow moment in reading. The thing that I don't understand about the book is that what make it so boring to read and I know that it have long word or the never get to the point part but more then than that. I think people think the book is boring because when the peoples read the book the character in the book don't suit there personality like for example: Elmo kill the whole people by farting and peoples might think this is offensive to them by reading this book. And I have read a lot of book that have a lot of cures word in there that I don't like to read like Being A Slave book there is powerful word but not the feeling that I don't feel inside the character.
