John de Lancie, Michael Brockhoff and Laurent Malaquais tried to make a Documentary to introduce and explain to people the phenomenon of bronies. They wanted to make an insightful, respectful and entertaining piece of media, where people who watched it would say: "Huh, that's actually pretty neat, now I understand."
I think they definitely succeeded! And they did an amazing job.
Even if some people weren't completely satisfied with what they were given, it was still a good documentary. (Is there even such a thing as perfect?)
The team had a clear vision of what they were trying to accomplish, and if you take that into account, the documentary was heading just the right direction.
As far as I know, they said they weren't going to include extended interviews because of piracy (read the Kickstarter page for more info)...
I'm very glad they decided to include them despite what has happened. Please show the team that you appreciate their work by NOT downloading this somewhere on the Internet. Buy it, it truly deserves every cent you pay for it.
