Who doesn't love cartoon animals, at least from familiarity if not vocally?
Some people go beyond the familiar, and want more than what the mainstream serves up. These extra-devoted fans have carved out a space with its own quirks and history.
Furry fandom has been overlooked as more than a curiosity for a long time, even with warmer outside media looks in recent years.
I don't care very much about "Furry 101" introductions. The Fandom could be one, and feels light to watch (thanks to care in using modest resources for a nicely edited professional feel), but it isn't insubstantial. It adds quite a bit of depth.
The best aspect of the doc is the loving care put into unearthing archival footage and digitizing old VHS tapes, then setting it against contemporary interviews of the same subjects today.
As time goes on, much of that past would be forgotten without an effort like this. Everyone is lucky that it exists.
There are some criticisms that this has PR appeal and skirts contentious subjects. A documentary that addresses every aspect of decades of activity is a magical unicorn. I would advise ignoring or taking those criticisms as unavoidable. There's lots of room to welcome different takes, make your own media, or do research elsewhere.
It's sad that this doc lost momentum with hopes to gain distribution due to pandemic shutdowns. It deserves better. It's very worthy of being on Netflix. Give it the time it deserves.
