"Psychological Thrillers are not a new genre of movies and have been around for decades, however, the 21st century has seen the refinement of this category with movies which are beyond praiseworthy. What sets this genre apart is its unique ability to engage the audience in such a way that they feel the emotional turmoil of the characters to an exceedingly empathetic level and see how they cope and navigate challenges they are faced with.
Not only can movies of this genre be unsettling, but they also excel at leaving the audience full of questions, and second guessing themselves, and allow them to expand the parameters of what they think is going on with the plot. With adept use of misdirection, unreliable narrators, vivid, and often non-linear storylines, these movies challenge the audience's scope for understanding the convoluted plots."
