"Ma" is a truly disturbing film. In this psychological-horror flick starring Academy Award winner Octavia Spencer, a lonely middle-aged woman befriends some local teenagers in her small Ohio town and lets them party in her basement. But there's a catch: they have to follow her rules. Soon enough, though, Ma's place goes from being the coolest hangout to a horrific dungeon when her "friendship" becomes a terrifying obsession. Beneath Ma's cruelty lies a traumatic tale of the horrors of being one of the only Black people in a predominantly white space, adding an extra layer of depth to this unnerving film.
