This episode had an excellent script, which really set it apart from the rest of the episodes of the last two years. This is expected, as it was Steve Carell's final regular appearance, and the episode was written by Greg Daniels. The acting was some of the best of the series, and it really came out as Michael held back emotionally, as he went to each employee to say farewell.
Season two opened with The Dundies, in which this episode established that the employee award ceremony of the same name was something that just about everybody hated, making Michael that less likeable of a boss. In the five and a half years since, some things have changed.
Back in season three, the employees were all invited by Kelly to join her at a Diwali celebration. At the celebration, Michael was introduced to Hindu culture, and learned about arranged marriage and how quickly Kelly's parents got married. Michael then proceeded to propose to Carol in front of everybody, which caused an awkward moment for the two of them.
The Client was one of the best episodes of The Office in accurately and fully representing Michael for who he is. In the main plot, he singlehandedly saved the branch with his phenomenal sales skills, and ended up spending the night with Jan. When Michael wanted to tell jokes, Jan limited him to just one, and he ended up phoning Pam to get a joke from his joke book.
Since Andy made his debut on The Office, he had always taken the role of a character with an odd side to him. But with Jim and Pam not awake enough to pay much attention, and Andy remembering quite well what it was like to be cheated on in a relationship, Andy ended up being the voice of reason in this episode.
It is typical for Michael's poor decision making abilities to have repeatedly affected the office in negative ways. As the years have passed, Michael has slowly learned to question his judgment, and to take the time to listen to his employees. "Body Language" is one of those few episodes where Michael is shown to have grown over the years.
