Yurgon,
I came to think the same thing after 2-3 episodes. It seems that the story repeats itself (and it is in some ways, although the situations slightly differ from one case to another (child to be rescued, landing zone cleared or not, interaction with ANP and ANA...)).
Probably they could have shown more in 6 épisodes. I'm not sure and I don't know. What's for sure is that the time has been taken to follow each of the presented cases of intervention and each of the protagonists. That last point is what probably creates the feeling of a show.
That doesn't take out anything from the fact that it is a good documentary and that these guys deserve our respect
