Confessions of a Shopaholic Movie

Tweet

Has anyone seen this new movie? I am almost finished reading the first book, and I want to finish it before I see the movie. I also have "Shopaholic Takes Manhattan" here, and I can read that too prior to seeing the movie. Does anyone know (without telling me what happens) how much the movie includes of the books in the series? Do I need to read more than just the first two to cover what is in the movie? Is the movie just based on the first book, or more than the first book?
