The background of Sassoon's life is interesting and the creation of his iconic hair cut (using German Bauhaus influences) was both educational and entertaining. Sassoon speaks with such warmth and passion that one cannot help but take part in his joy of looking back.
However, the film begins to take continual missteps toward the end. Difficult aspects of his life are glossed over; his three divorces, the death of his daughter to an overdose, the fact that he regrets selling his company, potentially negative views of his strict professional code, are all left untapped. Instead, the film inserts useless information about his health regime and closes by nearly deifying him for his charity work while his fourth wife sings ceaseless praises about his character.
The first 2/3rds build the story of an interesting man, who worked with endless determination to become the icon of his profession. But the film is afraid to let us actually know who Sassoon is. Stopping short of giving us depth by further examination of his failures and tragedies, the film heaps worship upon him. Regretfully moving the film away from being Sassoon's personal history and instead making it his personal highlight reel.
