The written introduction says, "We dream us back to great-grandfather's forests. At a time when simple human fist useful work gave a different closeness to nature. A quiet today we are struggling to get back to." according to Google translate. It suggests that the older way of life in the forest (much what the Bushcraft movement aspires to) was a lot simpler than it is today, and enabled us to get closer to the natural world around us, and that it seems it is not so easy for younger generations to get back to that way of life.
I haven't put that very well but its the best I can come up with at the moment.
Its also a vehicle for some stunning outdoor and wildlife footage. There's a number of films in this 'series' and I've seen one or two of the others and they've all been well made and equally well worth watching.
Mastino has it; beautiful!
