It may not be a work of great literature and it does come across a bit cliched in parts, but that doesn't mean the points made are not worth remembering, nor that a brave dying man is not worth admiring. Considering you can read the entire book in just over an hour, it's certainly not a great effort, and much more worthwhile than an hour watching sitcoms or reality tv. It's good to be reminded of our own mortality and what's important sometimes.
