I have not read the story on which the series is based. To the extent that the filmed version aims to represent historical fact in linking fictional characters to real ones, it is successful. Whether the linkage is correct or appropriate is another matter. Some of the filmed elements ring true, while others seem disjointed -- almost as if the scriptwriter intends to play with the viewer's mind. Non-linear storytelling is often like that, aiming for contrivance rather than narrative.
Taken strictly as theater on film, it is a highly entertaining piece of work. The camera pursues the protagonist (as played by three different actors) with a compassionate yet critical eye, inviting the viewer to pass judgment on his character by selectively picking out key episodes irrespective of logical development leading to foregone conclusion. This can be a sometimes gut-wrenching experience, not suited to lazy acceptance of questionable motivation on the part of a flawed hero.
To put it simply, if there is any moral to the story it pales by comparison to a theme of accidental and ineluctable passages in the life of a minor player on the stage of history, enhanced by backdrops of larger-than-life public figures and horrific events from the twentieth century.
Watch it for great acting and superb cinematic design rather than mere pleasure.
