Welcome to the twenty-first century. Are either of these films accurate or comprehensive portrayals of their time? Not even remotely. But they reflect cultural attitudes surrounding women, motherhood, and work, and the putrefied trope of Heigl's character didn't exist in 1987. Heigl and Keaton's characters are analogous as white-controlling-educated-women-who-have-careers-plus-family, and the evolution of this character is telling. Where Baby Boom gave hope, Life as We Know It brings despair.
