I have been a visitor in psych ward settings going back to the years when some were called “nursing homes” and state mental facilities. Many different experiences from the late 50s to the 2010s. I never had a stay so I have seen it only from outside the actual experience. Things have changed drastically over that time period from my perspective with several different types of illness and individuals. Some of what was portrayed in the movie was factual at the time. The problem is that people who never had an interaction with the system “see” the characters in the movie when they look at mental illness.
