Being a food fanatic and self-labeled gourmet cook, I found the movie to be a delight from the rip-roaring culinary successes to the meltdowns that all serious cooks have had.
I felt that Julia Child's portrayal was something of a caricature, even though Meryl Streep had the mannerisms and voice of Ms. Child nailed. There were enough serious aspects of Julia Child's life that she could easily be the subject of a "biopic" that would give a more honest and well-rounded portrayal of her.
The audience at the feature that I attended was mostly middle-aged and older. They seemed to appreciate a film that wasn't dependent on car crashes, murder and mayhem and pervasive foul language to carry a story.
