This doesn't say much about what they've actually done so far. They say it's "currently in production", but don't specify what that means. Have they interviewed anyone? Who? Who's agreed to be interviewed? It's going to be a very different documentary if they interview Taren Stinebrickner-Kauffman and Carmen Ortiz.
If it's still in production it might be that even they don't know it all yet. I have a lot of experience with that kind of work (conducted over 200 interviews for documentaries last year alone). More often than not you make a story in research phase only to find out that's really not the case once you start interviewing. Then you find yourself a real story, but you have to start from somewhere. Synopsis in documentaries is more of a Wishopsys, real script comes through interviews. One reason to conduct real, thorough, questions during interviews and not during research is so that you get genuine response. Making a documentary is a like a game of table tennis. You go back and forth numerous times during production and post.
The trailer that they have there seems to show that they've interviewed quite a few people. But yes, they did not mention who they will interview as a result of the funding and what the funding will allow them to do. They should definitely touch on that.
It would be good if they can get both sides and views in the same documentary.

Not necessarily. It depends on what the story in documentary is about. Absolutely nothing wrong with one POV in documentaries. Real devil is editing and narration which isn't structural in its function. By structural narration I mean narration written only to shorten some prologues to sequences in the story structure itself. With narration and editing you can distort your story in any way possible. I found out, through experience, that with sensitive subjects it's best to avoid narration altogether and tell story only through editing. Careful editing, where you weave story only through what you've been told by carefully selected interviewees.
