Slow but emotionally creepy, Hulu's 'The Path' portrays family life inside a cult

"The Path" is a slow but steady new drama from Hulu about a family in Upstate New York that is deeply enmeshed in a self-help movement called the Meyerists, a commune with all the telltale signs of being a scary cult. But "The Path" comes on gently rather than sensationally, as subtle as a ring at your doorbell and the offer of an informational pamphlet.
