Viewers branded the series an "expensive flop," citing the use of modern language and phrases that are inappropriate for its 11th-century setting.
Many viewers expressed disappointment, with some turning off the show midway through, calling it "complete, utter nonsense" and a "waste of talent."
James Norton, who also executive produced, defended the series, stating that "great drama" sometimes requires creative interpretation due to conflicting historical accounts.
Critics, including The Independent, largely gave the show negative reviews, describing it as "unwatchably dark" and the lead performances as "bland."
