The New Met Production of Parsifal

Back from the 5+ hour HD thater performance of "Parsifal." The music and singers were  incredible, but IMHO this new production by Francois Girard was a travesty, devoid of all luminosity and packed with blatant and idoisyncratic symbolism. With music so ethereal and shimmering, why is everything so dark and sere?  This is an opera that cries out for the masterful use of light, a la John 1:5,  but Girard instead gave us gloom; nirvana rather than salvation.
