** spoiler alert ** 
 This is a great premise for a book. The entire human race gets a two minute glimpse at what they're doing twenty-one years into the future. Some people like what they see and some hate their futures. 
 Unfortunately, by concentrating solely on a couple of storylines regarding scientists who accidently caused the flash forward, the book doesn't quite deliver on the world of possibilities it could have. 
 Some of my favorite parts were the the footnotes about what some people had seen. For example, there's a mass email plea from the future president of the U.S. telling everyone to stop emailing him that he's going to be the president. 
 Plus, it never addresses a core problem introduced early in the book. One of the main character gives a very scientific arguement that the future is set and that it can't be changed. What everyone saw will come to pass. However, later in the book, some changes are made and some characters change their fates, but others are doing exactly what their visions showed. No explanation is given for how some people are able to change their future while others can't. 
 I've read that a TV pilot is being filmed that's based on this book with the idea of telling how a variety of characters react to the various fates the flash forward shows them. That could be a very cool show that could live up to the potential of the main idea.
