I had similar feelings on the film after screening it last night. I have never read the book, and definitely would like to now, but the whole time I was watching the film I felt as though it was lacking. It had great potential in all aspects, but seemed flat and a bit disjointed. I agree that there were too many subplots they unsuccessfully tried to cover and as a result nothing in the film got the time and development it truly required for a significant impact. I did enjoy the actors performances, and am really curious to pick up the book and dig deeper into this story.
