What's the problem with Oz drama?

Why is the popularity of Australian drama shows waning? Maybe it's the kind of people being chosen to write the scripts. Andrew Bolt has written a profile of a very prolific scriptwriter, Marieke Hardy. As you might expect, she is a trendy lefty, who supports the Refugee Action Committee and other such causes. What you might not expect is the utterly low-natured way she chooses to express herself, especially for such a young woman.
