I learned that TDWP is someone I work with's favorite movie, so of course I had to watch it. Twice. Since the movie was based on a book, of course I had to read it. Just once so far; I'm waiting on the sequel to become available electronically at my library.
TDWP is a fast, fun read. It reminded me of a time when I worked at an institution headed by a powerful, fragile genius. Fun fact: the powerful, fragile genius of my past has a small role in the movie. Of course this person was no Miranda Priestley, but they did drive an assistant to tears over something minor.
Protagonist Andy Sachs is believable and likable, even when she gets sucked into the vortext of her powerful fragile genius boss. In case you're wondering, plot points are pretty different in the book vs. the movie, though much of the essence is the same. The movie's ending, however, is tidier and far different from the book's.
And btw, Meryl Streep is at her best in the film. Her "That's alls" are chilling.
