We asked fans of POV to help us find the "greatest" documentaries of all time, and this is what we found...

"Thor Heyerdahl's adventure was grander than anything my boyhood brain could have conceived."

"[It] was, by turns, quirky and smart, comic and thematically serious, very personal yet highly entertaining, with an auteur's voice stamped indelibly on every frame. It was pure revelation."

"In someone else’s hands, this story could have been a horror of exploitation. There were so many perils in this material. But Kate Davis shows us the power of film to humanize and radicalize."

"Maybe it’s not a documentary, per se, without characters and human narrative, but it’s a bit of non-fiction filmmaking that provokes more thought than any other I’ve ever seen."

"When I was first considering taking a leap into the professional abyss of filmmaking, there was one documentary, more than any other, that shouted out, 'Come on in, the water's great!'"

"His film is the hidden source that feeds the river of personal documentary filmmaking."

"I remember clearly thinking this was a 'game over' moment," says Detropia co-director Rachel Grady.
