WRONG. I WAS WRONG.
This movie is absolutely charming from start to finish. It is a brilliant script by Nora Ephron and a magnificent performance by Miss Streep. I realized halfway through the film that I was NOT watching Meryl do "another impersonation", but rather, she was BEING the character. And that is the essence of acting: inhabiting the character. Both Streep and Amy Adams are superb. And don't forget the wonderful Stanley Tucci!
The whole thing is a delight, even the soundtrack with Doris Day and Margaret Whiting singing as only they can.
Bravo to all concerned in making this treasure of a movie.
One bit of advice: do NOT go to see it if you are hungry!
Here's the trailer for you to enjoy:
