Battle and bloodshed are frequent on the show, as is romance, which sends a message that love is inextricably mixed with drama. Chivalry, liberty, and love of country is frequently championed, but these ends are usually accomplished through violent means.
Infrequent but gory scenes of injury and surgery, including squirting blood, internal organs, and a man screaming in pain. Battles are frequent and frightening; weapons including guns, swords, clubs, and knives are used.
Sex is frequent and quite explicit with breasts and buttocks bared, thrusting, moaning, and oral sex graphically implied. A woman marries two men, due to time-travel factors.
Infrequent cursing: "hell," "damn." A woman frequently utters the oath "Jesus H. Roosevelt Christ."
The series is based on a book series, which viewers may want to read after watching the show.
Characters frequently drink and refer to being drunk; this all happens in a historical setting.
