7 Best R-Rated Thrillers of All Time, Ranked

Thriller movies have a habit of getting under audiences' skin. The best in the genre tell a compelling story and give viewers the distinct impression that something could go very, very wrong, whether that's due to a killer hiding in plain sight, a criminal operation spiraling out of control, or a protagonist slowly realizing they have walked into a trap. Over the years, some of the genre's most acclaimed films have earned an R rating, which gives filmmakers the freedom to explore dark subject matter.
