What’s On Tonight: Hulu’s ‘Sasquatch’ Searches For The Extraordinarily Weird Truth

Sasquatch (Hulu series) — So officially, this is a documentary series, although the Duplass Brothers are behind the project, so you gotta know that the show’s approach will be anything but straightforward. The series promises to dig into a gruesome triple homicide that was allegedly carried out by Bigfoot back in the 1990s. Investigative journalist David Holthouse promises to tell the craziest story that he’s ever heard, even after his undercover dives into Nazi groups and violent gangs. He heads back to the Redwoods (and the infamous Emerald Triangle) in search of the truth about those homicides, and somehow, there’s a bunch of cannabis involved, and that could directly be tied to the murders This title arrives on April 20, so that (and the tone of the trailer, with distorted voices and a purposefully over-dramatic approach) probably tells us a lot.
