Once upon a time, a man named Douglas Adams wrote a brilliant novel called Dirk Gently's Holistic Detective Agency. A few years later a British television series arrived that was inspired by this book and really rather good, even if it wasn't a direct adaptation of the book. It was promptly canceled after only a few episodes. Then a few years later BBC America took a stab at the license and created a new show based on the book. In typical American fashion they opted for over the top nonsense like secret CIA projects and slapstick humor to appeal to audiences. Unfortunately, this worked and the show continued for two miserable season before it was canceled. This makes Dirk Gently's Holistic Detective Agency the only book I know of that spawned both a great television show of the same name and a completely horrible one. I suggest you don't confuse the two.
