I couldn't wait for the movie to come out because I loved My Life in France and Julie and Julia so much and because Nora Ephron writes good stuff and makes good movies.
The source material is so rich and alive that it could have and should have been made into two completely different movies. It must have been a hoot for the director to make the two into one and juxtapose as they did, and it was nice, but lacked the depth of feeling that came with each. So, if you haven't read either book, you will probably like the movie. There are some great lines and Meryl Streep seems to become Julia Child, she's so good at it. Four stars because of Streep and the subject matter.
Of course now I'm at home trying to perfect beurre blank.
