On Halloween, me and my girlfriend watched a load of spooky / horror movies, including Willy's Wonderland, The Conjuring 3, and Little Shop of Horrors.
Highlight, however, was Happy Halloween Scooby Doo! I recommend any and everyone to watch it. It has Aliens and Predator references, Elvira, Mistress of the Dark is a guest star, and there are even points where it seems to be riffing on Mad Max Fury Road. It's awesome!
