A collection of archival film and video, with some more or less related interviews interspersed. There is no real narrative structure underlaying the series, no sense that it has a director or a production vision.
Watching the first episode, viewers can think that a story - a narrative - is beginning to form, but then we're jolted into a completely other direction, with a different timeframe and different people involved. We scratch our heads wondering what happened. Did we fall asleep and miss something?
The subject is so rich in material, it's too bad that this is what F1 put out for its anniversary. But, maybe it's because Ecclestone still had a lot of sway at the time.
F1 still has a problem that it has not reckoned with, and that is its British bias. As it strains against these constraints, the Old Brit White Men (and other Old Men) work harder to maintain their power, their elitism, their misogyny and their prejudices.
This sloppy pseudo-documentary is a great display of that heritage.
Knowing a fair bit about F1 before viewing this series can help you enjoy the archives and, somewhat, the interviews. Know that you'll need to fill the many, many gaps. Also know that you're unlikely to learn anything new, and that there are much better resources for leaning about F1.
