Ah my man, hard disagree on “videos exist by themselves”.
Even if you have video, or oral accounts of something they are as flawed as the human condition is. The difference is the amount of bias, but they all have it.
In the documentary you’ll have the directors/production company trying to portray whatever they want to portray. In the oral accounts you’ll still have a skewed view, bound to that particular person’s experience. Sure in a sense can be more genuine, but should be scrutinized also. Who is the person? What is his participation in the events? Possible interests? Which social class? Etc…
We must not deny the bias, but embrace it. If we can gather as many different sources as possible, we should be able string a better perspective, but doing so also carries our own bias.
Nothing is neutral. And we don’t lose anything by admiting it.
They are right. We eat babies and kick the elderly, don’t we?
