The appeal of documentaries lies in the reality of its story, so whether it's heartwarming, political or downright strange, documentaries should always be true. Unlike fiction, which can immerse us in tales equally odd or awe-inspiring, non-fiction has an extra level of thrill, because "Oh my God, that really happened," we're bound to say upon the conclusion. The following 5 documentaries will have you uttering those very words, with enough twists, turns and shocking revelations to keep you invested in the story.

1.) Tickled (2016)

Tickled is a recent documentary by David Ferrier and co-director Dylan Reeve, two New Zealand journalists eager to unleash the truth behind a very strange sport called "competitive endurance tickling." Upon first glance, the sport seems harmless (and homo-erotic with only strong, young boys competing), but when the founder Jane O'Brien refuses Ferrier's interview with homophobic threats, he and Reeve jump down the rabbit hole that is Jane O'Brien Media. With weird sexual undertones, hidden identities and levels upon levels of bizarre, Tickled will certainly end up tickling you.

2.) The Wolfpack (2015)

The Wolfpack tells the story of the Angulo brothers, six kids whose father locks away in a New York apartment, unable to leave. Truly incredible, the brothers let their imagines run free by obsessing over movies. They create their own costumes out of cereal boxes and duct tape, memorize scripts by heart, and record themselves acting out the films on their own. While they've left the apartment on very short trips in the past, we watch them visit a cinema, a beach and an apple orchard for the first time in The Wolfpack.

3.) The Imposter (2012)

The Imposter, if never seen before, is a must-see immediately, because I'm about to spoil the story. It tells us of Frédéric Bourdin, a man who habitually steals the identities of children. His motivations aren't perverse, but instead, according to him, a desire to feel the familial love he was never given as a child. In The Imposter, he impersonates a missing child from San Antonio, Texas by the name of Nicholas Barclay all the way from Spain. How he nearly gets away with it, and manipulates the family after he's discovered as an imposter, is crazy.

4.) Who Took Johnny (2014)

Who took Johnny Gosch? To this day, we don't know. In September 1982, paperboy Johnny Gosch left his home to perform his regular route in his West Des Moines, Iowa neighborhood, never to be seen again. Only his wagon, left-behind newspapers and little dog Gretchen were found. Most definitely a victim of a kidnapping, as the narrative unfolds in Who Took Johnny, we learn there are possible ties to a pedophilic prositution ring and a whole hoard of other conspiracies, though no one's sure of the truth. The world may never know who took Johnny.

5.) Jesus Camp (2006)

Jesus Camp shows a cult in action under the guise of religion. The founder of an Evangelical Christian summer camp called "Kids on Fire," Becky Fischer, indoctrinates children to praise God, Jesus and the Word. However, a lot of what the children learn, such as climate change denial, raises immediate red flags: Kids on Fire wasn't created to spread the loving Word, but to spread an ulterior agenda that gives religion a bad name.
