Common Sense Note
Parents need to know that this version of the classic Alexander Dumas saga has plentiful swordplay and mortar fire, with some fatalities and bloody wounds. Also, expect brief scenes of punishment by whipping/branding and a fatal strangulation (but no gore). Female characters wear cleavage-baring costumes. There is some drunkeness and a strong sub-theme of religion used to inspire war and murder.
Bosomy costumes on women. One character may have started out life as a prostitute.
Sword thrusts and knifings, some fatal, plus battlefield explosions, rifle fire, and personal combat. Female characters suffer a whipping and a strangulation, non-explicitly shown. Finale involves an execution by beheading, happening at a distance.
"God" as an exclamation, "damn."
Hypocrisies and pretensions of the upper-class and religious orders are underscored. Religion -- Christianity, here -- proves a handy tool to manipulate assassins and destroy enemies in cruel political maneuverings.
Drugs / Tobacco /
Social drinking and occasional drunkenness.
