The show appears to take notable liberties with casting choices and character revision, often highlighting identity over the tightly wound plotting typical of Christie’s mysteries. Some elements feel shoehorned to show off modern tropes rather than advance the narrative, with classic suspense occasionally sidelined in favor of contemporary ideological messaging.

Traditional values, particularly the era’s family and social norms, seem minimized. There's a clear revisionist streak in how gender roles and social relationships are modernized, with old-fashioned morality gently mocked or dismissed. Christie’s original setting is given a progressive gloss that feels out of place.

Dissenting or traditional viewpoints are generally presented in an unflattering light or sidelined altogether. The characters default to modern attitudes, with little debate or internal conflict. Any alternative worldviews are typically personified by unsympathetic caricatures, offering little real ideological diversity.
