If there’s a message here, it’s that siblings who might seem as though they have nothing in common can, if given the chance (or a quest), reconnect. But apparently they need to do lots of raunchy stuff and kill men and monsters alike in bloody battles before they find common ground.
Creatures are beheaded and shot with arrows, struck by electric currents, pummeled into a pulp, clubbed into submission, gored, speared, and more. Some of the battles get pretty gory; you name the torture, they show it -- though it's all played for laughs, of course. There's also a joke about being molested.
Pick a scene, any scene, and there’s likely to be a sex joke in it. Bare-breasted women are shown, and a woman’s backside is shown as she dives into a lake. Tons of references to sex of all kinds. A minotaur, with his genitals visible, humps a man; later, another character cuts off the creature's member and wears it around his neck.
Profanity galore: “F--k," "s--t," "whore,” “slut,” “piss,” "prick," "t-ts," "ass," "hell," "damn," “d--k,” "goddamn," and "c--k" are all here, and many other combinations thereof.
Princes and creatures smoke what appears to be weed or some sort of hallucinogenic. Also some drinking during revelries and celebrations.
