Think of it as “Contemplative Time”
If you can’t cut around bad acting, the best you can hope for is to be saved by your cutaways, and by the reaction shots of other actors. Another alternative is to rewrite the scene on-the-fly to be one of those moody contemplative scenes with billowing cloth and slow-motion cigarette smoke. I suggest you grab lots of cutaways, though.
Amazing how much the video for Total Eclipse of the Heart and The Hunger resemble each other. Ah, the joys of billowing cloth, slow-motion doves, slow-motion cigarette smoke, and slow-motion violin playing, combined with slow camera dollies.
