If you don't know much about Churchill, then I don't think this is ths best starting place.
This mini documentary series is a personal memorial to Churchill by some of those who knew him. It gives a different perspective on him as a man, particularly in his latter years.
There is little detail about Winston's career. It is more an exploration of his character and the enduring love of the nation towards him. It was espescially moving to see footage of the cranes lining the Thames, bowing in succession, as Churchill made his journey to his final resting place.
For anyone who already has an interest in Churchill. This series does offer you something new.
