Doug Dillaman’s review published on Letterboxd :
I'm a sucker for process cinema, and watching old Swiss dudes (and one young Swiss dude) (and one woman) spending 96 minutes making charcoal in the traditional manner was as satisfying as I expected. Fritz Hauser's enigmatic melodic percussion soundtrack is a definite plus. I would say that it's lacking that something special to distinguish it, be it the Herzogian eye for the obscure telling detail or more of a surgical sense of composition like Geyrhalter. Nonetheless, I was never bored, perhaps because in part the space gives one's brain room to wander. In some ways this is a great counterpart to BRIMSTONE AND GLORY, another story about a town whose fiery traditions keep it alive yet find challenges fitting into the modern era.
