Mare of Easttown premieres Sunday, April 18 on HBO and HBO Max. This is a spoiler-free review. [poilib element="accentDivider"] HBO's new deliciously dreary crime series, Mare of Easttown, starring Oscar-winner Kate Winslet as an emotionally weighed-down detective in a blue-collar crevice of Pennsylvania, is a chilling and thrilling piece of Neo-noir. Like famous Dennis Lehane books-turned-movies Mystic River and Gone Baby Gone, Mare of Easttown is a mystery that rests on the frustrated, reluctant shoulders of its unhappy characters, who are resentful of their monotonous lives and overwhelming responsibilities.
