Thrillers.

THRILLER FILM GENRE It is difficult to state a clear definition of a thriller because thrillers cross over many genres of filmmaking. Thrillers can be divided into countless categories; e.g., action thrillers, psychological thrillers, crime thrillers, spy thrillers, romantic thrillers, supernatural thrillers, etc. However, the single greatest characteristic of a thriller is the obvious one.

If you can't turn away, if it has you biting your nails and staying up late at night, double-checking that the windows are locked and worrying and fretting about whether the characters are going to survive, chances are it is a thriller.
