In the ninth episode of the first season of Netflix's The Crown, Graham Sutherland paints Churchill's portrait as an 80th birthday gift from Parliament, but Prime Minister Churchill hates that portrait, in episode : (as per google Sutherland's Portrait of Winston Churchill)
The presentation ceremony at Westminster Hall was recorded by the BBC. In his acceptance speech, Prime Minister Sir Winston Churchill remarked on the unprecedented honour shown to him and described the painting (in a remark often considered a backhanded compliment) as "a remarkable example of modern art", combining "force and candour". Other reactions were mixed; some critics praised the strength of its likeness, but others condemned it as a disgrace.
After that, the conversation between Prime minister Churchill and Sutherland is not clear to me why Churchill doesn't like that portrait!!? (may be its because English is my second language I couldn't understand it properly [there're many plots which I fail to understand yet.]
So my question is "Why does Churchill hate his portrait"?
