This is a good portrayal of what happens to a person that realizes that they did horrible things and now have the guilt to carry.
Mitch wants to be a better person even though he knows that he will carry the weight of his sins for the rest of his life. This does not excuse the severity of his mistakes but the show wants you to see what happens after a person's life is destroyed by their own doing.
The media world is taught will not forgive even thought people want to do better.
I read someone say that Jennifer Anniston and Steve Carrell's acting was terrible but I have not idea what that person think talent is.
