Yes! We're all cheesy when we're sincere and I feel like people can sort of take refuge in that, always looking for ways to avoid it in either direction. It makes me think of an article in TVGuide many years ago that was about not quite the same topic. It was looking at characters that started out broadly comic but wound up having more sincere, vulnerable scenes so they could sustain that sort of sincereity. People get especially squicked when it's done badly but I think everybody really longs for it to be done right. So avoiding it isn't the right way either.
