I think the top ten is solid except for the omission of Heinlein and the inclusion of the nihilistic Douglas Adams. Considering it’s NPR, the list is not bad at all.
There are a few eyeroll choices, and the descriptions are very tendentious (Starship Troopers is “controversial” yet man-hating The Handmaid’s Tale isn’t “controversial” at all)
How is Starship Troopers controversial?
Oh ya mean the part where citizens have more rights than the leaches.
Douglas Adams is one of the authors that you either love or don't understand what the fuss is all about. I personally agree with you, I found the Hitchhikers series to be dull, not particularly witty or funny, and essentially pointless. However, my two brothers absolutely love the Hitchhikers series, think it one of the best series of all times. To this day they still quote lines from the book.
I don’t think a book being controversial is a bad thing at all. People are still whining about what Heinlein was saying in STARSHIP TROOPERS, but who the heck reads the dreadful HANDMAID’S TALE today?
