If you watch the beginning of each show, there is always a different Director and Writer that gets credited.
With the Writer-I don't know if the person has a team or writers and that person gets credit, but it truly is different each week.
The last show about Beth was written by Eboni Freeman. Directed by Ann Fletcher who was an
American dancer, actress,
choreographer and film director. She is best known for her films
Step Up (2006),
27 Dresses (2008) and
The Proposal (2009). Eboni does not have any credits listed on Wikipedia. What I am trying to say, is I think the producers bring in writers and directors that know what they are writing about and directing. So some people do not like some of the shows as much as other ones. This probably explains why some shows are so different.
