Reception

edit

On the review aggregator site Rotten Tomatoes, 76% of 34 reviews are positive.[7]

Variety reviewer Courtney Howard states, "Writer-director Russell Goldman re-fashions the puzzle box constraints of his short “Return to Sender” into an intricately-faceted feature, making way for a deep character study to emerge, crawling under our skin to truly unnerve in its damning examination of how commercialism is insidiously interwoven into our daily lives. Boldly off-kilter, brilliant and bizarre, its dark humor and taut psychological horror are laced together in a delightfully heady blend."[8]
