The Slap (2008)

An adult hitting someone else's child at a barbecue sends consequences through a network of families and friends. Eight perspectives expose loyalties, resentments and private conduct that make public opinions less simple. The value is watching people defend different boundaries, not being asked to give every defence equal moral weight. It is abrasive and sexually explicit, with racism and child-directed violence. Choose it for uncomfortable disagreement rather than reassuring mediation.
