[19] In reviewing the album for Pitchfork, Quinn Moreland wrote: "Duffy sings of romances come and gone without ever sounding jaded or spiteful; future love promises a mystery, a sensuality that’s open like the road".

[41][42] Of the album, Paste Magazine writes, "these chapters are personal, droll, flushed and cresting; wondrously experimental and deftly consummate; a skyline of everydayness... Duffy paves a new slate, growing slowly into subversive song constructions and articulating how a body might begin tumbling through familiar habitats with a romantic, curious and joyous eye.
