Creating a Documentary

I was researching about making a documentary film and the biggest hurdle is the story.  I was thinking more like a paper or print but with film it is the story and character.  So a film about DRM who is the character and the struggles?  Well then I could put the character as someone that is the victim?  My curiosity on the technology and its affect on the end users?  I think the latter might be the way to go.
