I'm still behind on reviews from 2007 so this will be short.
Mediocre isn't the best word, but it's the first word that comes to mind.
Repetitive isn't the best word, but it's the first word that comes to mind.
This is the first Palahniuk that I read, and I wasn't very impressed. The first and last couple of chapters were well written, but the rest was kind of boring and repetitive. Example: near the beginning of the book he mentions that "deja vu" has an opposite, "jamais vu." Interesting. A few chapters later he mentions the same thing, but not in an offhand or clever way, he just copied and pasted the same paragraph that I had read 5 chapters ago. It's repetitive, did I mention that yet? So in then end, what could have been a great book comes off as demeaning, as if he assumes the readers are dumb.
