Criminal is one of the most gripping crime dramas ever made. It's unique format really nails the intensity of the situation and, as we already know the police have got their criminal, we're thrown deep into the detail of how the cops get them behind bars. Aside from the intensity of the script, it's perfomances are simply stunning. Whether it's the conveyor belt of stars such as Kit Harrington and Sharon Horgan playing the criminals, the duty solicitors trying to protect them - or the familiar faces of the police - everyone on set brings their absolute A game. Katherine Kelly plays DI Natalie Hobbs, and here she discusses what a fantastic experience both watching AND making the show is. Criminal is available on Netflix now.
