I have not seen all of it or paid attention to it in full detail. I'm not very up to date with the whole situation either and am not up to date about what's been told or not before. I felt I've heard some fragments of what's being told elsewhere from other people but was not sure. However it did seem to give me some sense of David's character and personality.
Overall it felt to me like it got progressively more speculative and fringe which I thought was a little bit surprising. The documentary felt like all the stories we heard were true, and they're trying to speculate about and rationalize all of it leaving nothing behind.
