I opened this book expecting it to be like the movie (which I don't particularly rate). I was suprised to find out that the only similarity was lead characters name. The book, simply, sh*ts all over the movie. Robert Neville has more depth, he doesn't have a dog, doesn't listen to Bob Marley, he's a drunk and the vampires are something very different (much more dangerous than in the movie) What a great read! Glad I bought it!
