Heavy on awkward recreations with actors but regrettably light on interesting historical detail. The main draw of this series is mainly some newly refreshed and colourized archival footage.
The four episodes lean heavily on British and American political figures, including an Obama speech writer, President George W Bush and Prime Minister Boris Johnson - rather than on historical experts. Of course, this is consistent with the tone of an "approachable" and "greatest hits" approach to history documents. It's a decent introduction to Churchill and the period, but there's little to chew on.
In just one example, the series correctly focuses on Churchill's obsessive quest to get the "New World" - America - fighting in the war. However, after showing Pearl Harbour, there's no mention that Herr Hitler foolishly declared war on the United States first - a key footnote that enabled Roosevelt to bypass Congressional wrangling.
All too typically, with a laser focus on FDR and America, the series doesn't even mention the valuable support of Canada, Australia, India and other Commonwealth countries in helping keep the British Isles afloat.
Also, it would have been fascinating to see some of Churchill's military interactions with his senior generals and commanders - and the kind of expectations he had on them - but this is out of the scope of this series.
So while watchable, and crediting star Christian McKay for a solid job recreating Churchill's oratory, this offers a rather lightweight overview of what can be a very meaty subject.
