Despite a disclaimer slide warning that some North American cinemas might experience transmission interruptions, the broadcast went smoothly for once, nearly six hours of it. Great performance of a Wagnerian masterpiece that is in a league of its own! But the AMC 25 is apparently going to take at least a month to repair an escalator used to assist patrons down from its lofty cinematic heights, and the foyer of screening room 17, where "Parsifal" was shown, smelled as if someone had recently used it as a toilet. Aren't more effective cleaning products available to movie "palaces"?
