    The Deep Dive: Raise your hand if you’ve ever had an existential crisis waiting in a Disney park line.

    The Atomic Café

    Runtime: 1 hour, 26 minutes

    The Premise: Added to the National Film Registry in 2016, a full-length restoration of this 1982 cult classic documentary is now available on YouTube. With dark humor, it deconstructs a dark chapter in history.

    The Deep-Dive: Weaving together Cold War archival footage consisting of newsreels, commercials, government propaganda, and military training videos, The Atomic Café depicts the startling misinformation being fed to the public regarding the dangers of nuclear war. There are even clips from instructional videos telling people to “duck and cover” in the event of a nuclear explosion. This blast from the problematic past pairs well with a viewing of Oppenheimer.

    The Premise: The world champion of a complex Chinese board game plays against an AI-generated opponent. Man and machine are put to the test in this documentary that is more than just fun and games. 

    The Deep Dive: Believed to have been created 2,500 to 4,000 years ago, the chess-like board game Go is as competitive as it is challenging. This award-winning 2016 documentary digs into the history of the popular game, highlighting its intricacies and the brilliant minds who have mastered it. Because the game relies heavily on human intuition, the ability for a machine to master it is considered a technological achievement. Chronicling the lead-up to a definitive face-off between South Korean Go champion Lee Se-dol and his computerized opponent, AlphaGo, the burning question is: Does artificial intelligence threaten to replace every uniquely human quality?

    In Search of a Flat Earth

    Runtime: 1 hour, 16 minutes

    The Premise: This documentary explores the archaic conspiracy theory that the Earth is flat rather than spherical. 

    The Deep Dive: Flat out: this documentary by the Folding Ideas channel isn't flat-Earther friendly. Creator Dan Olson takes viewers on a journey to Lake Minnewanka in Alberta, Canada - revered as a specific spot that supports the flat-Earth theory - to debunk the theory himself. It's a fascinating experiment that illustrates not only the curvature of the Earth, but also the details of an infamously divisive topic.

    The Deep Dive: The title of the documentary might sound like a tabloid headline, but unfortunately, it's absolutely true, because FTX and Sam Bankman-Fried, initially heralded as a crypto-genius, created massive crypto-ruin. Released the week before Bankman-Fried took the stand at his fraud trial, the documentary offers a walk-through of the events that turned his financial legacy into a cautionary tale. Whether or not you actually comprehend how cryptocurrency functions (or doesn't function), you'll be astonished by the greed and arrogance that brought down this man and his company.

    The Dark Side of the Silk Road

YouTube creator Barely Sociable dives deep into the sordid tale, showing all the receipts, and asking viewers to “hold all opinions” and what they've previously read about the unraveling of the Silk Road until the end of the video.

    The Pemberton Incident - An Unsolved Mystery

    Runtime: 48 minutes

    The Premise: Deep in the Canadian back country, hikers find a burned car along with personal items that belong to a missing person named Marshal Iwaasa. The discovery links his disappearance to the case of another missing person, Daniel Reoch, yet neither of them are any closer to being found. 

    The Deep-Dive: Intriguing from start to finish, this investigative documentary explores two disappearances in harrowing detail. Riddled with suspicious evidence, inconsistent narratives, and incompetent authorities, the story is as compelling as it is frustrating. Perhaps if the police put as much time into solving the case as Barely Sociable put into making this documentary, the case would be solved.

    Runtime: 1 hour, 13 minutes

    The Premise: This documentary tells the tragic tale of the SS El Faro, a ship that sailed directly into a Category 4 storm near the Bahamas in 2015. Perhaps even more tragic - and infuriating - is that the incident could have been avoided. 

    The Deep Dive: This high-quality documentary delves not only into the mechanics of the ship, but also the human complacency that steered it to its doom. The detailed breakdowns and thoughtful animations make it easy to follow, even if you're afraid to see the perilous ending. It may have you yelling at the ship's captain on your screen, but it's certainly worth a watch.
