The Tenant: Great Polanski film, really captures the cabin fever feeling of staying in an apartment dolo for too long and the way the your sense of self starts to melt
The Wickerman: Classy, manages a really creepy atmosphere with zero bloodshed
Don't Look Know: A slow burner, first time I watched this I was actually starting to nod off then the last 5 minutes of the film jumped me out of my shyt good n proper, one of the GOAT horror endings
Dead Of Night: Fantastic portmanteau film full of ideas, creepier than a 1945 film has any right to be, yall need to peep it ASAP
The Abominable Doctor Phibes: 1971 Vincent Price evil genius vehicle with the fukkery set to 11, but some of the deaths in this and the sequel are still pretty foul by today's standards
Brain Damage: Frank Henenlotter classic, scenes in that movie that have anyone I show it to
without fail
