yeah, that was a bummer....
but from reading Julia's writings, and those about her, how she never did promotions for products because she never wanted to compromise herself, and how she was indeed from another generation, I was puzzled by that and did some research. The Julie blog (it's still up if you want to read it) is profane with lots of F--- this and that.
Julia's publisher brought it to her attention and discussed it with her and she was not pleased with that.
Yes, she didn't read the blog and have a grasp of the whole, but I think from what she was told, it was really repugnant for her. She hated people "using" her and was always on the watch for that.
That's why I think she said what she did--which was, condensed, "she isn't a serious cook, and she was disrespectful" That did not come out in the movie. We just heard the Julie actress saying "she hates me" which is not what Julia said.
And I totally agree. I didn't like the way that was handled. It wasn't a clean happy brush up to it.
