I know we aren't supposed to take chick lit seriously, but this book made me angry for the messages it sends out. I had zero sympathy for the main character, but I had even less sympathy for her annoying friend and boyfriend, who seemed to have a really hard time understanding that she couldn't be there for them 24/7. Most of the characters are flat. I was unable to even raise up any real ire directed at the editor, due to the cartoonish way in which she was presented. The ending of the book feels rushed and tacked on, and I really wasn't buying it.
I haven't seen the movie, but I understand that it improves on the book (really, it would be hard not to.) I can't recommend this; there are better chick lit novels out there.
