Query: One Flew Over the Cuckoo's Nest

Very intense, well written novel depicting the type of care used in the treatment of mental illnesses.At this date, it seems almost implausible that such a cold, calculated and cruel approach was considered therapeutic.But if one looks over the history of treatment of mental illness through many years, it was just another step towards a more humane approach, even though what is being used at the present day is still far from perfect.
