Another factor particularly notable in the films and novels of the time is the use of North of England situations, accents and themes (for example Rugby League, the iconic sport of Lancashire and Yorkshire). This combined with a frankness about sex, and a more political content (sometimes descending to rants), to mark a rather clean break with the assumptions of 1950 in the arts generally.
Kitchen sink drama is sometimes conflated with the rise of the Angry Young Men. It was in fact more substantive, less driven by journalistic excess, and is more properly its successor.
