Today is St. Patrick’s Day and do you know what that means?! No, it’s not the holiday time when we all indulge in those suspiciously-sweet lime green concoctions called McDonald’s Shamrock Shakes. It’s an apt occasion to surf the multitude of the best streaming services for a selection of hauntingly-good Irish horror flicks and series to shake the shillelaghs from you and your mates.
The Emerald Isle is notorious for nerve-rattling movies centered on superstitious legends and folklore featuring restless spirits, marauding monsters, lascivious leprechauns, and strange woodland creatures. If you’re looking for something other than Darby O’Gill and the Little People or Finnegan’s Rainbow to watch this St. Paddy’s Day, check out my five fright-filled picks below.

Some truly unsettling occurrences are afoot here, lurking just underneath the placid surface of this charming town which was the site of several disappearances 25 years ago during the annual Festival of Samhain, the Irish Night of the Dead.
