It does have some fans, many of whom seem to share your opinion by the way. I just could not get into it. And I tried considering that everyone was telling me how funny it gets and "oh if only you were to read a few more pages it would get awesome". This persisted since page 20 until I gave up around page 80.
You would tell me if praise for this book is just a giant in-joke, right? I'm on the fence about returning to it sometime.
