Lovely--beautifully done. I would have gotten to the subject a little sooner. The opening street shots bugged me a tiny bit. They were pretty for the sake of pretty and didn't seem to advance the subject.
Also--and this is an observation, not a criticism--it's kind of the utopian version of being a luthier--great space, plenty of leisure, little apparent routine or tedium. It's entirely coincident with his point of view--handwork is better, paying someone else to do it is worse than doing it yourself. These things might be true, but if you do everything yourself the result is dilletantism. The workman is worthy of his hire--mastery of luthiery is beyond me, and I see no good reason why doing it myself is necessarily better than paying a master craftsman. A documentary could aso include the "downside" and some would say it should--the tedium and routine, the frustrations with customers/clients, the tension between handwork and innovation with tools and machines that as far as I can tell every luthier experiences. Your film expresses, it seems to me, a utopian anti-modernism.
At the same time it's beautifully done and the point of view it expresses is certainly an admirable point of view and I'm not unsympathetic to it.
