“Lights Out” is a horror film released in 2016 that was directed by David F. Sandberg. The movie is based on Sandberg’s 2013 short film of the same name, which became a viral sensation online. The storyline follows the story of a family who is haunted by a dark entity that thrives in the darkness and turns off the lights every time it’s around.

The film’s protagonist is Rebecca, a young woman who is struggling through life even as she tries to take care of her younger brother, Martin, who is terrified of the dark. Martin’s fear is not just a fear of the dark, but also of the entity that hides in the shadows whenever the lights go out. As Rebecca begins to investigate the entity, she finds that it is linked to her family’s tragic past.

The family’s troubled past revolves around Sophie, their mother. The entity that torments the family has been tied to Sophie since she was a young girl, and she has never been able to escape its presence. Sophie’s mental health deteriorates rapidly, and she ultimately ends up in a mental institution.

As Rebecca works to uncover the truth about the entity, she becomes increasingly convinced that it is trying to take her family, just as it took Sophie’s life. Rebecca teams up with her boyfriend Bret and Martin and together they break into Sophie’s old workplace to get the answers they seek.

As they attempt to dispel the sinister entity, they are constantly battling the darkness, which the entity uses to its advantage. In a heart-pumping climax, Rebecca confronts the entity and discovers the disturbing truth behind its existence.

Overall, “Lights Out” is a nerve-wracking horror film that grips the audience with its suspenseful storytelling and brilliantly executed jump scares. The film’s exploration of mental illness and its impact on a family is an interesting focal point that adds depth to the movie’s plot. The vivid and macabre portrayal of the entity, coupled with the well-choreographed action sequences, make for a truly thrilling horror experience.
