The documentary is not intended to "unmask" Philip Roth in the sense that you learn every possible thing about him. What the film unmasks is the solitary life of the writer, the life of one who has become, as Manera articulated, "a self-appointed slave to his writing."
To younger writers who are missing the boat, I want to say: Read Roth. Learn from his oeuvre and from his life, and from how the two have intersected. Learn how a writer can keep pace with America and tell its story as well as his own, again and again.
Philip Roth may be our greatest living writer. So why would he give himself over to filmmakers who would make a movie as dull, superficial and pedantic as Philip Roth: Unmasked?
