Flatliners is a 2017 American science fiction psychological horror film directed by Niels Arden Oplev and written by Ben Ripley.

A stand-alone sequel to and remake of the 1990 film of the same name, it stars Elliot Page,[a] Diego Luna, Nina Dobrev, James Norton, and Kiersey Clemons.

Sony Pictures released the film in the United States on September 29, 2017, and was panned by critics, who generally remarked that it repeated the problems of the original in failing to do justice to its interesting premise.

She invites her classmates, Jamie and Sophia, to join her in an experiment, in an unused hospital room: using defibrillation to stop her heart for sixty seconds while recording her brain.

Courtney, traumatized by her visions, records a message apologizing and admitting that her interest in flatlining was due to the death of her sister, not for scientific discovery.

They admit the mistakes they made and come to the conclusion that their hauntings experiences are hallucinations owing to guilt from their sins, not the paranormal.

[6][7] Development would officially shift from a TV series to a feature film in August 2011; Source Code writer Ben Ripley was attached as screenwriter and Laurence Mark would co-produce with Douglas.

[17] Principal photography began in early July 2016 in Toronto,[18][19] Ontario primarily at Cinespace Film Studios' Kipling Avenue facility, and concluded on September 7.

Page also detailed instances of racism toward Clemons by a crew member, and queerphobia towards himself, notably from an unnamed head of production.

[27] In North America, the film was released alongside American Made and 'Til Death Do Us Part, as well as the wide expansion of Battle of the Sexes, and was projected to gross $8–12 million from 2,552 theaters in its opening weekend.

The website's consensus reads: "Flatliners falls flat as a horror movie and fails to improve upon its source material, rendering this reboot dead on arrival.

"[31] Metacritic, which uses a weighted average, assigned the film a score of 27 out of 100, based on 20 critics, indicating "generally unfavorable" reviews.

[29][33] Criticizing the repetitiveness of the scenes and lack of tension, Peter Travers of Rolling Stone called the film "even more witless and stupefyingly dull than the original."

[35] Matt Zoller Seitz similarly said that "[the] premise [of the original Flatliners], which could have opened the door to a visionary work of sci-fi horror, settled into a sort of gothic self-help drama groove, with the medical students realizing that the seemingly supernatural goings-on triggered by their experiments in 'flatlining' were manifestations of their past misdeeds.

Director Niels Arden Oplev's remake ... sticks to that template, changing key details here and there while embracing a style that stirs every current horror movie visual cliche into a jagged paste."
