A hard-R Marvel action-comedy that earns its rating immediately and sustains it throughout: extreme bloody violence, wall-to-wall profanity, and relentless crude sexual humor are the default register of the film, not isolated moments. Adults who know the Deadpool franchise know exactly what they are signing up for; everyone else should treat the rating as a genuine warning.
