Don't faint, but I actually liked Kay Francis in Dr. Monica. Usually I'm her biggest critic, but she did a good job in this entertaining drama. I found her much more believable as a career woman than as a mother, her usual role. She always seemed very self-absorbed to me, a quality that lends itself much more to a high rung on the ladder than a seat in the nursery. In this movie, she's a dedicated obstetrician with a supportive husband, Warren William, who also has his own career. They seem to have a perfect marriage and all their friends envy them.
All except one, Jean Muir. Jean is having an affair with Warren behind Kay's back. If you look the movie up online, you'll get major spoiler alerts as to the rest of the plot. I wouldn't recommend it; just watch the movie and let it unfold naturally. It's a very interesting story with a timeless struggle between the characters. And don't be surprised if you get a lump in your throat at the end. You'll also see Ann Shoemaker and Verree Teasdale in the supporting cast, and Louise Beavers in a small role as Jean's maid.
