It's a neat subject, but I think you may have missed m0nty's point, a perspective which I share, about "jazzing up" with unnecessary dialog. I just clicked on "Fish traps" and my ears are full of idle banter between the two people making traps and whenever they're quiet for more than a moment the narrator breaks in. Someone is speaking at all time and it's obnoxious. This complaint is entirely distinct from how comprehensively they cover subject matter. BBC historical documentaries are far from the worst offender in this area (American TV is far, far worse), but primitive tech does a much better job than the BBC of permitting the audience to simply observe and absorb.
