Hate to disagree, but I didn't think they did a good job on that video.
I'm always sceptical of any furry media, and I know it's better to leave it and not get worried about it. But, curiosity killed the skunk and I find myself looking at any documentaries that arise.
I like to think that I know a good amount about psychology and the like; after all, I do spend a lot of time thinking about and researching it. And one fact I do know is that for somebody to listen to your views you have understand their view on the matter. You also have to find a way of being as close as you can in personality and views to them.
Think about it, who's more likely to make me believe something, someone I know and relate to or some fanatic with a closed view on the matter?
You need a furry who is as close to today’s view of "normal" as possible... thus don't start your documentary interviewing Fursuiters, they're quite obviously too involved in the fandom for the sceptic's liking. I would say start with someone who is just a furry supporter or at the most has created a character, nothing above that.
Then, once you've sorted the basics (as we've all said to people: "Furries are just people who think cartoon animals are neat") move onto other levels of the fandom, like RPing and *CLEAN* artwork.
Maybe then, and only if the documentary has gone well for the viewer so far, move onto Fursuits and the way that they allow you to bring your character to life.
If you really want to push your luck, move onto the conventions and the complete innocence of them (ie: we don't all go for a furpile in a dark room, we go to hang out with friends, meet new people, view art and the work put into peoples suits).
In a clearly defined section of the documentary state how the fandom has been shown in the wrong media light and just touch on the negative reasons why, BUT do not go into detail.
I really wouldn't suggest putting any of the spirituality aspect in the documentary... How many 4channers and Facepunchers do you really think are going to be accepting of that?
Anyway, that’s my view on what a documentary should be. So I’ve indirectly said what I didn’t like about it by saying what (IMO) it should have done…
I’m starting to confuse myself now…
