Jumping into a novel in the middle of a series is never a great idea.
While the story was interesting enough, the humor failed to deliver.
On the second reading, a decade after the first, I finally got this book.
A book that is a rehash of a TV show could be disappointing, unless it is a really good TV show.
The temptation to abandon something you are not initially enjoying is not always something to heed. If you do, you may miss out on some pretty great things.
