Stupid books that you like

What are some books that have little to no literary value, that you have enjoyed reading?

Dan Brown's books. I can't speak for the Da Vinci code particularly, but if it's like his other books (Digital Fortress in particular) than it only sounds intillectual to those completley clueless about the subject. Luckily not many people are experts on Da Vinci's artwork or religious symbology.
