My favorites are a bit mainstream. I love to discover cult movies, hidden gems, that one movie that is completely bonkers.
The "Mask of Satan" version. A cult movie from cult director Mario Bava, staring cult actress Barbara Steele.
A lot of Italian horror is style over substance. Not this one. It has substance and style. A style that is copied a zillion times.
Gravestones, mist, cobwebs, dust, candles, thornbushes, torches, secret hallways, a crypt, ... Name a gothic cliche and it is here in it's fullest glory.
