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.
Like Monty Python, I’ve found that women don’t like Douglas Adams books (in general) while men find them hilarious. Just an observation. I’m sure there are plenty of exceptions among both sexes.
I can’t really say how it is received by the other 2 or 3 sexes that the California public school system currently recognizes. Ugh!
