Saw this show at the National Theatre last night. One of the most powerful, urgent plays I've seen in a long time, and maybe the most accurately reflective of women's issues in modern Britain. It's a gripping character study and state-of-the-nation piece in one. Sad, infuriating and at times bitterly funny. Great script, acting and set design, and deserved the standing ovation it got. 100% recommend it.
(I did see another post on here taking issue with some of the legal realities in the show - it is true that the play presents an extreme case in how a suspect might be treated by the police/justice system, but that's the point - the play is something of a parable, and is absolutely not (nor pretending to be) a legal drama. Even so, the way the legal proceedings are shown isn't particularly unrealistic or hard to believe - major spoiler for the end here: the main character is charged with violence-related offences after grabbing and shaking a child (who she didn't know beforehand) right next to a train track, which is likely what would happen. The play ends as the court case begins, so we don't know whether she'd be found guilty or not).
