I feel a certain resonance with that experience, since I started reading this book expecting a lightly humorous look at all that is cheesy (being addicted to several cheesy cultural phenomena myself, such as anime and 'flying people' movies). As I progressed into the book, I came to realize that one or two such essays were funny, but the more I read, the more mean-spirited it seemed. Yet I could not put the book down. In the end I finished it thankful that it was only 188 pages long.
Do yourself a favor and just pass this book by, unless you too have a rather mean-spirited attitude towards the trashier elements of pop-culture.
