Not sure what flavor you’re looking for but here’s some of the ones I enjoyed:

• Pan’s Labyrinth - fairy tale horror
• Gretel & Hansel -fairy tale horror
• Babadook - dramatic horror
• Mothman Prophecies - dramatic horror
• Hereditary - dramatic horror
• The Descent - adventure/action horror
• Jeepers Creepers - adventure/action horror
• The Mist - adventure/action horror
• The Crazies - adventure/action horror
• 10 Cloverfield Lane - adventure/action horror
• This is the End - comedy horror
• Shaun of the Dead - comedy horror
• Zombieland - comedy horror.

On my Halloween movie list this year I’m planning on watching

• Little Otik (fairy tale horror with stop motion & live action - looks artsy)
• Lamb (supernatural horror)
• Tigers are not Afraid (supposed to be similar to Pan’s Labyrinth)
• Midnight Meat Train (Clive Barker horror- one of Bradley cooper’s earlier movies)

Saw some other good ones already posted here - Event Horizon, Midsommar - so I think you’ll get a good list.
