Michael Fassbender plays Brandon, a young professional living in New York who harbours a sex addiction but has built a stable life around his vice. The arrival of his equally damaged sister (Carey Mulligan) shakes him out of isolation and threatens to send them both over the edge.
Fassbender is reliably brilliant, but really lingers in the brain afterwards is the sorrowful tone that seeps out of every frame. McQueen avoids heavy-handed moralising, but what we see on screen tells us everything about the burden that Brandon lives with. Unmissable, but probably not one to watch with your mum.
