If you saw the movie with Meryl Streep and Amy Adams then you'll probably be expecting a funny, quick read, which unfortunately is not the case. 
 What the movie managed to hide (at least partially) is that Julie Powell is one of the whiniest person who ever set foot on this planet. 
 The tragedy of her life is being a secretary for a governative agency involved in the management of the aftermath of 9/11: poor girl has to spend her days performing data entry and answering the phone calls of relatives of the victims or other (not always courteous ) concerned parties. Ok, so not so exiting but I can imagine much worse, especially for someone without apparent skill or qualification, whose only ability is complain about the miseries of her life and boast an aspiration to become an actress without ever having tried an audition. 
 Her famous Julie/Julia project is basically an excuse to whine and whine and whine about everything in her life even if she has a loving and very very patient husband, no health issues and a vast group of friends who inexplicably love her despite her being a self-centered, narcissistic bitch. 
 The 50% of the book is a list of all the culinary experiments which went wrong, basically because she faces them with carelessness, resignation and a vodka drink always in her hand. 
 Rather than a book this looks like a very very very long blog post, written by someone who fancies herself witty but simply suffers from verbal diarrhea.
