Netflix has released a horror movie so scary that people can't watch it until the end.

Veronica, streaming now on Netflix in New Zealand, is a Spanish horror film (with English subtitles) telling the story of a young girl and her siblings, who try to talk to their deceased father using a Ouija board.

You don't have to be very familiar with horror movies to know that using a Ouija board is never, ever, a good idea.

Veronica, played by Sandra Escacena, found out the hard way when she couldn't send the spirits back after her first attempt at communicating with her dead father, during a solar eclipse.

It'd be scary enough as a work of fiction but what adds an extra layer of spookiness to the film is the fact that it is based on a file from the Madrid police, about a girl who mysteriously died after dabbling in the occult in the early 90s.

The film has a 100 per cent rating on Rotten Tomatoes.

The quality is no doubt aided by solid performances from the child stars, including Veronica's young siblings, Lucia (played by Bruna Gonzalez), Irena (Claudia Placer) and Antoñito (Ivan Chavero).

The movie is directed by Paco Plaza, who had already shown his penchant for horror storytelling with the critically-acclaimed REC in 2007.

Social media users have been sharing their frightful experiences watching the movie.
