"There are many subcategories of the genre at hand, including action thrillers, crime thrillers, legal thrillers, and even erotic thrillers. But some of the most famous films of all time fall into the psychological thriller subgenre in particular. No titles of that caliber or name value — or anything by Alfred Hitchcock, to drive the point home — qualify for this list. Through keen eyes for camerawork, vast understandings of pacing, and widespread dedication to the art of building suspense, plenty of these directors should without a doubt be regarded as masters of the psychological thriller subgenre. Also: there are a ton of fantastic psychological thrillers from different geographical regions that won't make the cut as, obviously, they're foreign films that will inherently be viewed by less American audiences than those filmed in the English language. All that said: these are the most underrated psychological thrillers of all time, ranked." - movieweb.com
