The Rupert Murdoch Film Festival is more a homage rather than a diatribe. It attempts to focus on the evil mogul but inevitably slides towards adulation. What can you say about someone who voices The Simpsons line himself (4:15 in this video): "I am Rupert Murdoch, the billionaire tyrant, and this is my skybox!"
As the narrator Jack Shafer says, "Perhaps Murdoch's embrace of his depiction as a cartoon figure of evil and low scruples akin to Charles Foster Kane isn't a joke on Murdoch. Perhaps the joke is on us."
No kidding, Jack.
