The screenwriter Aline Brosh McKenna wrote the movie. I was not a fan of the book at all but the movie was excellent. Smart, funny and I thought Meryl, Emily, Stanley and Anne were great. The actors who played Anne Hathaway's friends and boyfriend, not so much.
I love the way Ms. Streep says "Why is no one ready?" and her silver hair looks fierce. A lesser actress would have made Miranda a caricature.
