Amazing images, but slowest movie ever - Silent Light

Silent Light is an extremely strange film, a film of extremes. First of all, I thought I'd misread the summary. Could this really be a Mexican film? The characters are Mennonites (exactly like the Pennsylvania Amish), they speak an obscure dialect, something between Dutch and German. The landscape is lush green, forested - nothing in this movie seems Mexican in the least. It looks Scandinavian, quite like an homage to Bergmann, and also (I've read) to Dreyer. Not only the look of the character but the austerity of their lives and the spiritual angst that the main character, Johan -father of the large (6 children) family devoted to his wife (Esther) but in passionately in love with another woman, Marianne (who's no beauty by the way), in their small community. Esther and pretty much everyone knows of his passion, and he anguishes about how to resolve his feelings, his faith, his family commitments. (In Bergmann, he would have killed himself.) Oddly, Esther "dies," but then, with a kiss from Marianne as she is literally laid out for burial, she comes back to life. Religious symbolism laid on pretty heavy, without anything in the movie leading you to think this would happen; the film is all quite realistic, an interior drama. No flying angels or anything. On the downside, I have literally never seen a slower-moving film in my life, more than two hour and, perhaps, 200 shots? I actually fell asleep, lying down and saying to Marge, I won't miss anything, then woke up (20 minutes?) and could pick it right up. The plus side: the director lingers on his shots lovingly, beautifully, and EVERY ONE is amazing, composed like a photo in a museum. The family in the stark white room for the funeral with the long silences of the mourners, the funeral hymn, the slow anguished painful breakfast scenes, the long fast drive on a straight dirt road, the farmhouse in the evening light, Esther standing in the pouring rain by the side of the highway, maybe most of all the (6-minute?) opening take of day breaking - I will never forget them. And the use of ambient sound - no soundtrack, only the lowing of cows, the song of birds, the chirping of insects, throughout, all the time. In some ways, absolutely amazing. This film doesn't quite work on all levels, its spiritual ambitions tripping it up a bit at the end, but it has things you will never see anywhere else. Who knew there were Mennonites in Chihuahua?
