Native Son

Native Son was really interesting but I was kinda dissapointed. I thought the plot line was pretty predictable. Let me stop now and try to explain that I am well aware that books aren't purely for entertainment and I have never been the kind of person to reject a book simply because it didn't keep me on the edge of my seat the whole time, but still. I felt like the plot for the book was really predictable. Again I also realize that the plot was more to make a point and show a situation from the troubled, young African American's point of view and show how poverty will greatly effect the well-being of people and the racism endured by African Americans during the early to late 1900s, I just felt like the plot was very unoriginal. Native Son was very similar to books like The Ghost of Mississippi and To Kill a Mockingbird and I guess I just expected a little bit more from it. Am I being shallow in my thinking?
