Just watched Train to Bursan and it was outstanding, it is Korean and has subtitles but totally worth the effort.
Also watching Dirty John which is about a bad divorce but ends of feeling more like a psychological thriller horror as most Christian Slater stuff does, like in Heathers where you are never really sure what exactly it is you are watching because of the glib charm. Pretty good Halloween choice for those who like the scary stuff on the lighter side, or at least I think so I haven't finished the story yet so it could get worse.
