Certainly inspired by the novel of the same name, and without reference to the book it holds up as a pacy historical drama.
But not much of the bookโs plot, character arcs and tone is found here. By the end of episode 2 I felt personally offended for what they did to Ellenโs arc, and Alfred is supposed to be a brute, not a schemer as portrayed here. The โrelationshipโ William and his mother have is, erm, an interesting interpretation of their characters. IMHO theyโve strayed too far from the source material and ended up with a substandard story.
A shame but that means the door is still open for a faithful retelling without repeating the watered-down characters and sub-plots found in this miniseries.
