Do you like 80s cheesy half-comedy horror? Re-Animator, starring the man himself, Jeffrey Combs. The first two are loosely based on the Lovecraft story, the third is an original script and goes completely off the rails, but in a fun way.

Cabin in the woods

Can recommend Color Out Of Space if you’re the type that appreciates a bit of Nick Cage. It’s Lovecraftian horror but somehow also has Tommy Chong in its cast.

And why not make it a more Cage-y by with Renfield and Longlegs? Throw in some Willy’s Wonderland and you’ll be golden.

Hereditary and Anihilation

Poltergeist

You should watch that “Cars for Kids” commercial on repeat. Pretty sure it will give most people nightmares if watched enough times.

Thirteen Ghosts

“Drag me to hell” had a bunch of gross and jump scares…92 on rotten tomatoes.

Cats.

House. Japanese movie from the 70s.

Sinister is my top pick for pillow hugging, eyes watering scary.

Happy Death Day is funny spooky

Train to Busan is the best zombie movie ever

Idiocracy

the best horror ive seen in the past several years were A Dark Song, The Night House, His House and Weapons
