The positivity from these two is quite refreshing, though, is it not? I think that's what people are enjoying.
It's quite nice knowing that K will turn up with an upbeat tempo, a smile, and impeccable manners, W will be statuesque and droll, they will both look good and say nice things - no moody Diana, no petulant H, no whiny M. People take pleasure in predictability, certainty, and consistency (probably because the rest of life is the opposite).
