I wanted to like this, but sometimes suspense movies scare me too much, so I read the book first. Easy read and I highly recommend it. The movie had too many holes that were easily filled in by the book. Characters were added (for no good reason) and major things important to the plot (like THE BIRDS) were left out. No wonder most people didn't get it. It's only 300 pages. It'll take a few hours. Your time will be better spent.
