Our world can be strange and dangerous—there are unexplained events, numerous dangers, and tragic violence that make it extremely terrifying for us who populate it.

These dangers are where we draw inspiration for the many thrillers that we consume. But while our imaginations can produce exceptionally gripping materials, reality is often much harder to beat. That’s why documentaries that tackle real crimes and other emotive events are soaring in popularity right now.

Best Thriller Documentaries

Recently, there’s been an increased interest in documentaries that provide perspective on the craziest, strangest, and most compelling real-life stories.

Why We Like Watching Thriller Documentaries

Thriller documentaries offer a window into the less desirable sides of humanity. While most fictional thrillers function the same way, there’s a reason why documentaries leave a lasting impression. The events you watch and the emotions displayed weren’t limited to the imagination, but actually left a mark in reality.

When you watch thriller documentaries, you get a close and intimate look into situations that would normally have you close our eyes or run away in fear. These tense and dangerous events give you a rush while you remain safe in the comforts of your home.
