A Steve Mcqueen film about sexual addiction was never going to be a barrel of laughs and ,yes, Shame might be one of the bleakest films to grace our screens in recent years. Luckily, it's also one of the best.\r\n\r\nMichael 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.\r\n\r\nFassbender 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.
