The film stars Aubrey Plaza, Dane DeHaan, Molly Shannon, Cheryl Hines, Paul Reiser, Matthew Gray Gubler, and John C. Reilly.

Once Zach wakes, he returns home to find a stranger in the house and burnt bodies in the backyard, which he believes to be his family.

He finds the house in disarray and discovers that Beth, now a full-fledged bloodthirsty zombie, has eaten Maury and some of Geenie's fingers.

Jeff Baena conceived of the idea of the film several years prior and it almost went into development with Joseph Gordon-Levitt in the boyfriend role.

The site's consensus states, "In spite of Aubrey Plaza's committed performance, Life After Beth remains a sketch-worthy idea that's been uncomfortably stretched to feature length.

[10] In a positive review, The Guardian critic Mark Kermode wrote, "Sensibly prioritising straight-faced weirdness over goofy gags, writer/director Baena keeps things just the right side of believable, eschewing explanation in favour of cracked domesticity.

John C Reilly and Molly Shannon are terrific as Beth’s gaily traumatised parents, but Plaza steals the show with one foot in the grave, her rotting heroine ricocheting between adolescent snarkiness and cadaverous rage, a lethal combination of which no one around her has the measure.

"[11] Richard Corliss of Time also gave a positive review, writing, "Plaza, whose wide-eyed stare suggests a zombie as painted by Margaret Keane, plausibly navigates Beth's journey into full-throttle Linda Blair demonic dementia.

"[12] In a more critical review, Brian Eggert of Deep Focus Review wrote, "Of course, in the long tradition of zombie metaphors, the whole movie stands as an allegory for dealing with the heartache of loss, be it the loss of life, or simply a bad breakup where the other party seems to become a raging monster afterward.

Though not without its fair share of charms and laughs, the central notion of zombie physical romance is handled in an unbelievable way.
