Yang, Ryan Hansen, Portia Doubleday, and Michael Rooker and follows a group of people who, while visiting the eponymous island, discover that their dream-like fantasies brought to life begin to turn into horrific living nightmares and they must try to survive.

Upon arrival, island proprietor Mr. Roarke guides the guests to their fantasies: Patrick is enlisted in a war in honor of his late father; the Weavers become honor guests at a mansion rave; Melanie takes revenge on her childhood bully Sloane Maddison; and Gwen accepts her ex-boyfriend Allen Chambers' marriage proposal, which she rejected many years ago.

"[23] Peter Travers of Rolling Stone gave the film zero out of five stars, writing, "If crimes against cinema merited prosecution, Blumhouse's Fantasy Island would go directly to death row...The only genuine, blood-curdling scream incited by this stupefyingly dull time- and money-waster comes at the end, when the notion dawns that [the film] is meant to spawn sequels.

"[24] Peter Sobczynski of RogerEbert.com wrote that the film "contains less raw terror in its entirety than Sonic the Hedgehog during any five minutes of its running time," calling it "utterly boring" and "no sane person's fantasy of a half-decent movie.
