It Ends With Us viewers given warning that film isn’t about what you might think it is

Warning: This article contains discussion of domestic violence which some readers may find distressing.

Unless you've been living under a rock for the past few days, you'll know that Blake Lively's latest film hit cinemas on Friday and fans have been going absolutely wild for it.

The movie in question, titled It Ends With Us, is based on American author Colleen Hoover's 2016 novel of the same name.

Check out the official trailer here:

Now, the film is clearly getting some rave reviews from fans and critics alike but, for anyone who is yet to tick it off their 'to-watch' list, you've been warned that it isn’t about what you might think it is.

The plot sees us introduced to Lily Bloom (Lively) and Ryle Kincaid (Justin Baldoni).

Lily, a woman who overcomes a traumatic childhood to embark on a new life in Boston and chase a lifelong dream of opening her own business, happens to spark an intense connection with charming neurosurgeon Ryle following a chance meeting.

However, as the pair begin to fall deeply in love, Lily begins to see sides of Ryle that remind her of her parents' relationship.

Everything then changes when Lily’s first love, Atlas Corrigan, played by Brandon Sklenar, suddenly reenters her life as her relationship with Ryle is upended, and Lily realises she must learn to rely on her own strength to make an impossible choice for her future.

It Ends With Us has been marketed as a romance - yet it's clear the contents of what plays out is far from a fairytale.

And one viewer has taken to Instagram to warn of exactly that.

The woman, who goes by the handle @sarahthebookfair, took to Instagram to share her views on the allegedly 'appalling' and 'unsettling' marketing of the flick.

Sarah began: "If you are planning to go see It Ends With Us, I urge you to please really look into what it's actually about before you go see it.

"It is being marketed as this romance movie, as this rom-com, as this, like really cutesy little story. It's not."

She then issued a 'trigger warning' before sharing with prospective viewers: "This is a movie about domestic violence, and the way it's being marketed is not reflective of that at all."

Sarah warned that if someone was planning to see the film without knowing that, then they'd be 'completely blindsided'.

"So if you didn't know that, now you do, and you can make an informed decision on whether or not it's a movie that you want to go see," she continued before adding that she was 'appalled' at the way It Ends With Us has been marketed.

"I'm appalled and disgusted, but simultaneously and unfortunately, really not surprised," Sarah rounded off.

"It's all been very unsettling to say the least."

Tyla has contacted Sony for a comment on the film's marketing.

It Ends With Us is currently available to watch in cinemas across the UK.
