David Tennant as Dr. Liang being the protagonist in this movie has set a very unique example of treating psychological illness through simplistic means. This movie set in 1960s opposes orthodox approach of psychiatry then with that of unconventional means such as simply establishing a common ground of communication with the patient, paying attention to their behavioral patterns and many more to comprehend the root cause of their illness. They deserve the kind of attention that any so called "normal" person in a society is entitled to which I have come across in some of Dr. Jung's books.
I would suggest to patiently watch this movie in order to grasp the underlying essence of this movie.
