Most critics rate it highly, and the praise clusters almost entirely around Jack Nicholson’s McMurphy, described across the reviews as charismatic, electric and among the strongest work of his career. Forman’s direction, the casting and the feel of the ward come next, and Louise Fletcher’s Nurse Ratched is repeatedly picked out as frighteningly convincing. Several reviews note the shape of the film: a loose, funny first half that slides into tragedy.
The reservations come from two directions. Writing at the time, Pauline Kael in The New Yorker finds it effective pop mythology rather than great art, and Roger Ebert thinks it weakens whenever it reaches for symbolism over character observation. More recent critics, Time Out and The Playlist among them, complain of a simplistic picture of mental illness, a streak of misogyny and a final triumph that rings hollow. The spread is narrow; nobody dismisses it, but the dissenters are not fringe voices.
