Reception. Critical response. Steve Pond of "TheWrap" pointed out that "cohesiveness or coherence are not high on [the film's] list of attributes", "but [the film's] messiness is part of its charm". David Ehrlich of "IndieWire" gave the film a 'B+' score, concluding that "always compelling, but sometimes more sedate than its material demands — [it] is often at its most alive during its detours".
