Here's a list of some thriller documentaries to watch on Netflix that will make you question humankind and leave you shook!

As much as we try to avoid feeling scared, thriller documentaries do have a way of making their way into our lives. You'll be terrified to the core but still won't be able to stop watching them till the end. What about them makes it so appealing to watch? All of these Netflix true-crime thriller documentaries are sins committed by our fellow citizens of the world, and it's just human nature to be curious about what happened in another person's life. It's a major reality check that our world is not a garden of roses or the little fairyland we were made to believe it was but an eerie society where some really disturbing individuals also reside.

Thriller documentaries show us what a daunting task it can be to get into the psyche of these evil masterminds and find out the root cause behind what really pushed them to become these monsters. Some of them manage to give us an acceptable answer but some keep us awake for nights together almost making it feel like an unreal ghost story. Keeping the gruesome realities aside, thriller documentaries can be a great genre for binge-watching as the story has you on your toes right from the trailer itself. The real-life footage, interviews, editing, and pictures have the ability to make the audience feel like they're a part of that room, watching the whole story unfold right in front of their eyes.

Warning: The fear level in all of the documentaries in this list is quite high and it's not for the faint-hearted. We recommend you watch these along with someone!
