I'm yet to see this film and not expecting a masterpiece, but the idea of a two-tier society (minus the elites) operating in such close quarters is very much a reality heading this way.

⁣Class struggle becomes all too real as a young doctor moves into a
modern apartment block in suburban 1975 London. Drugs, drink &
debauchery dissolve into murder, mayhem and misogyny in this
pseudo-post-apocalyptic breakdown of societal norms.
