What: "Who killed Laura Palmer?" was the question at the center of Twin Peaks, a murder mystery cult classic about the eerie secrets hidden within a sleepy town in the Pacific Northwest. Cancelled after only two seasons (but revived recently for a limited run in 2017!), the show is known as one of TV's all-time greatest, and features an unforgettable cast of quirky, eccentric characters.
Why: Twin Peaks was a staple of early 90s popular culture, and set the tone for many atmospheric mysteries to follow (think Top of the Lake, The Killing, and even Riverdale). At the heart of the show is the unforgettable group of teenagers who find friendship, romance, and rivalry after the death of their classmate, Laura Palmer, and discover complex and varied ways to deal with their grief, fear, and anguish.
