If you've already seen the movie, you still need to read this book! The basic premise is the same, but the characters and details are totally different than the movie. I thought the movie was pretty freaky and wasn't sure if I'd enjoy the book it was based on -- I actually liked the book better! It's translated from Japanese, but the writing flows and the story is so engrossing I couldn't put it down. I finished it in two days. Now i need to get the others in the series to see what happens next.
Better than the movie, I'm sure. ^_^
I saw the movie (the American remake) a few years ago. I don't remember it perfectly, but I think the story as told in the book is slightly different.
I didn't think the book was great. OK, but not great. Maybe because it's a translation, or maybe because it's just so-so. I kept reading it because I wanted to find out what happened next, not because the prose was particularly enjoyable.
The copy I have has a nicely designed cover, though. Probably my favorite part of the book!
