From a discussion on Goodreads' Catcher in the Rye site about books that are "overrated."
It occurs to me that there is a lot of difference between, "I didn't like this book" and it is "just junk"
I am reading Wuthering Heights right now in another group. The complex psychology of the main characters is amazing. I've thought about a time in my past when I took a path which was obviously so wrong for me and wondered what I could have been thinking? As I study Heathcliff and Cathy, I gain some understanding of what was going on and, what is more important to me, I understand that I could not have taken any other path at that time because the outcome of that choice is what made me a different person.
It is all right that a person doesn't like the The Catcher in the Rye or Jane Austen or the Bronte's, but it doesn't mean that they aren't good books and don't deserve to be classics.
On the other hand, there are many books on the New York Times' best seller list that I do believe are overrated because they contain no plot, poor research and poor character development.
