This is the movie based on the book by the same name. And it does live up to the book. It suffers from the same malady that movies based on books typically suffer–too many shortcuts, and no ability to understand what the characters are thinking as the plot moves along. But this movie does a pretty decent job, and the main characters–Melanie and Dr. Caldwell, are very convincing, indeed.
