Viewers say terrifying and disturbing new horror movie is going to ‘f*** people up’

Horror fans who have already plucked up the courage to see Smile in cinemas have warned that the film is so terrifying that it's going to f*** people up.

If you're not sure whether you can handle it, check out the trailer first:

Smile tells the story of Dr Rose Cotter (Sosie Bacon) who, after witnessing the traumatic suicide of one of her patients, starts experiencing frightening occurrences that she can’t explain.

It isn't long before Rose realises that the demon who stalked her patient is now after her too, and it's taking over her life.

If she wants to escape her horrifying new reality, Rose is going to have to confront her troubling past, and make an impossible decision.

Those who have already braved the film in cinemas are seriously impressed with the new film, calling it 'one of the scariest movies of the year', with perfect jump scares, and a 'looming sense of dread' that sticks with you long after you leave.

At the time of writing, Smile has a score of 76 percent critics' score on Rotten Tomatoes.

"Smile is gonna f*** people up. Truly. Deeply. F***. Them. Up," tweeted one fan after checking out the new horror.

"So many terrifying, disturbing images: hardcore horror that doesn’t hold back and never flinches."

Another impressed viewer raved: "#SmileMovie is one of the scariest movies of the year with shocking imagery, many well executed jump scares & a looming sense of dread felt throughout."

A third penned: "#SmileMovie is pure horror scary crazy creepy edge of my seat the whole time lot of jump scares one of the best film I've seen this year. Definitely check it out this weekend."

And a fourth warned: "There's one specific moment (you know the one) that is gonna be nightmare fuel for a long time to come. It was actually petrifying."

Speaking about the film, director Parker Finn has said: "I wanted to see if I could turn a smile into a threat, something that feels dangerous and evil and see if I could use that to creep audiences out.

"I wanted to set out to make something that was deeply frightening and feels like a sustained panic attack from start to finish."

Mission accomplished.

Smile is out in cinemas now.
