I was apprehensive in watching the movie, as I chose not to read the book. Even though I respect S. Harvey, I question his philosophy on men and women and the dynamcis of "hooking up". I heard many different reviews about the book when it first came out, have to admit some I did agree with and some i did not. Fter many good reviews from friends an co-workers and the hubby REALLY wanting to see the movie, I gave in and must say AWESOME movie, with good story line, characters, actors and humor. Enjoyed thoroughly with my husband, but would also enjoy with my girlfriends. Will see again very soon.
