The problem with this line of thought is that the job of a school is not to ensure that students aren't bored or to let students read what they want but rather to educate students and prepare them to enter society.

While I don't dispute that there are themes in Puzo that can impart life lessons, it's hardly the best way to show students the craft of literature. A good teacher will find a way to relate the classics to things that interest the students.

There are certainly differences of opinion on what is great writing, but those decisions are better made by teachers than high school students.
