heartumentary
Often seen on PBS and at film festivals, a heartumentary is a documentary with heart. More than a documentary, which chronicles data on a particular person, place, and/or thing, a heartumentary not only informs the audience but gets them actually caring about the person, place, and/or thing.
This weekend, at the local film festival, I saw an excellent heartumentary, "Plagues and Pleasures: The Salton Sea". Watching it made me care about the place and the people and animals who live there. Since The Salton Sea is in danger of extinction, it also makes me want to let others know about it.
