horror documentaries based on true stories

Not always. Some documentaries might take creative liberties or present one-sided views.

The sense of authenticity. Knowing that these events actually happened makes it scarier. For example, in 'The Act of Killing', the fact that the killers are re - enacting their real - life murders is both fascinating and terrifying.

Another great one is 'The Imposter'. This is a truly disturbing story. A French man impersonates a missing Texas boy. The documentary shows the real - life interviews and the strange events that unfold as the imposter tries to fit into the family, blurring the lines between truth and lies.

The fact that they are based on real events. People are often drawn to the idea of the unknown and the real - life horrors that others have faced. It gives a sense of authenticity that fictional horror doesn't always have.

One such documentary is 'Cropsey'. It's based on the real - life urban legend of Cropsey on Staten Island. The documentary delves into the mystery and the real - life events that might have inspired the terrifying tales.

Well, it depends. Some are quite reliable as they are based on real investigations and eyewitness accounts. For example, documentaries related to the Warrens' cases often have a lot of research behind them.

One of the top documentaries based on a true story is 'The Act of Killing'. It's a chilling exploration of the Indonesian mass killings in the 1960s. The film has the perpetrators re - enact their crimes in various cinematic styles, which is both disturbing and thought - provoking. Another great one is 'Blackfish'. This documentary exposes the treatment of killer whales in captivity, especially focusing on Tilikum, an orca at SeaWorld. It led to a significant public outcry against keeping these large and intelligent animals in such confined spaces. And 'Icarus' is also very notable. It started as an exploration of doping in sports but turned into a much bigger story about the Russian doping scandal.

One great one is 'Icarus'. It delves into the world of doping in sports. The filmmaker originally set out to make a film about his own attempt at doping to compete in a long - distance cycling event. But as he dug deeper, he uncovered a major international doping scandal. Another is 'The Act of Killing', which is about the Indonesian mass killings in the 1960s. It's a very powerful and disturbing documentary as it gets the actual perpetrators to re - enact their crimes in different cinematic styles.

Another good example is 'Serial'. It focuses on the case of Adnan Syed. Each episode dives deeper into the mystery of his conviction for the murder of his ex - girlfriend. It's interesting as it presents different perspectives from various people involved in the case, including Syed himself, his friends, and family members, and also those from the legal side.
