Query: Nice try, doesn't work

Two stars might be a bit harsh for this novel, but then again Ishiguro isn't some first time author so I penalize him a little more. I agree with the reader who said this should have been a novella unless Ishiguro could have come up with something more substantial for a plot. He creates a nice air of menace hovering in the background, but the day to day lives of the characters simply aren't interesting enough to sustain the first half of the book. I've noticed something interesting about many of the five star reviews--they seem to be reviewing the book's criticism of runaway technology without moral guidelines instead of the book itself. They're not wrong necessarily, but if a book is boring I'm not going to enjoy it no matter how much I agree with it's main point. Some people read for other reasons I suppose.
