Why read this explainer

Compare Chief Bromden's distorted inner account with McMurphy's public conflict against Ratched. Removing that narration changes the escape's perspective even though the event remains.

PlotGeeks note

The Chief's escape remains, but removing his narration shifts attention toward McMurphy's fate. Public conflict takes the place of much of the surreal interior account.
