Melissa McCarthy as Michelle Darnell, a titan of industry who is sent to prison for insider trading. After doing her time, Michelle emerge, but not everyone she steamrolled is so quick to forgive and forget. Michelle is forced to move in with former assistant Claire and her young daughter, Rachel. Now at her lowest point, Michelle devises a plan to rebuild her empire. I and others have said that Melissa does the usual stuff and I still feel that way but she has been changing up on her characters and they have been tons of fun. The Boss is no exception, she plays a woman who stepped on everyone to get to the top and now at rock bottom she has to change her tune or does she? She wants a family and could her previous employee and her daughter be that? The entire support cast is superb. From Kristen Bell and Peter Dinklage and Kathy Bates to the girls who make the cookies. I got many laughs out of this movie.
