Movies Like Aftermath That Horror Fans Need To See

2016's "Lights Out" is another movie about an imaginary friend who turns out to be real, evil, and terrifying. This time, however, it's the children who catch their mother talking to someone who doesn't seem to be there, a presence she calls Diana. Maria Bello plays Sophie, the mother, Teresa Palmer plays Rebecca, her adult daughter, and Gabriel Bateman plays Martin, Sophie's young son and Rebecca's half-brother. As for Diana, she only appears  when the lights are turned out (played by stuntwoman Alicia Vela-Bailey in terrifying makeup) and vanishes when they're turned back on. With those simple rules it seems easy enough to avoid her — until, of course, she manages to cut the power to the entire neighborhood.

"Lights Out" is a greatly expanded remake of a 2013 short of the same name made by the same director, David Sandberg. After the short went viral on YouTube (via Daily Dead), Sandberg received multiple offers to make a feature version. Unlike the short (and most other films of this type, like "Z") 2016's "Lights Out" goes to great lengths to explain who Diana is, where she came from, and how she came to haunt this particular family. Your mileage may vary when it comes to the backstory, but the scenes of Diana moving as a silhouette in the dark will freak you out either way.
