I rented this movie because I am a Rob Pattison fan. I have never read the book. I was not sure exactly what to expect either.I have to say I was completely involved in the movie. The 3 main characters played had great rolls and did a great job. I would recommend watching the movie--but this is not a movie that I would by and watch over and over again.I am an animal lover, and some of the scenes were a bit cruel to the animals, whether they were real or computerized.Rob and Reese didn't have the passion like I think they should have. That could have been better too.all in all, it was worth my money to rent it and watch it at least once. I can say it was not a waste of my time :)
