Doctor Foster (2015)

"Doctor Foster" is the BBC drama that turns a quiet marriage into a slow-burning psychological war, tracking a betrayed wife as suspicion curdles into obsession. Suranne Jones anchors the series in the title role, delivering a performance that swings between composure and raw unravelling. The tension bleeds into the bedroom too, with 3 scenes on site capturing her in nude and sex scene territory that strip the drama down to something rawer than the dialogue lets on. It's a show built on betrayal, and Jones commits fully to every layer of it.
