Despite featuring some wonderful interviews and archival footage, I Am Your Father is ruined by the film-maker's senseless insistence on inserting himself into the film.
The film has a fascinating story at its heart - that of David Prowse, who played Darth Vader in the original Star Wars trilogy and remained remarkably unrecognizable despite playing one of the most iconic characters in all movie history.
Yet the central story - that of David's all too human journey and disappointment - is elbowed out of the way so the film-maker can indulge in some wish fulfillment.
While I understand the temptation for the film-maker to become his story, particularly given Star Wars' place in the Pantheon, the Michael Moore approach weakened the film and turned what should have been a richly poignant piece into just another ho-hum documentary. Pity.
