I think my rating would be a 3.5 or 3.75, possibly a 4, if I had read the book instead of listened to the audio book. I really struggled with the over dramatization of the actors, especialy the one reading the female voice. 
The first part of the book I really thought I'd rate it a 5 I was enjoying it so much. However, the writing became a bit repetitive, overly dramatic, and dull. I also became annoyed at how whiney the main female character was, but that may have just been the way is was read.
