Netflix has dropped a new Spanish horror movie, Veronica, which has been described as the “scariest movie ever”– and viewers are going mad for it.

The movie was put online earlier this week (February 26), and people have taken to Twitter to warn fellow users about their nail-biting viewing experience.

One user writes: “Started watching Veronica on Netflix […] but the demon walking down the hallway scene freaked me out so much I had to turn it off”.
