You know the song. It is a significant part of Christmas prepaires and Mariah Carrey just shines one more. But this version has the gift to be not only a nice updated version but to explore entire atmosphere of holliday, from the soldiers from Nutchcracker to the candies, polar bears and the reaction of surprise and joy of kids. Sure, a lot of kitsch , large slices of commercial but huge effort and inspired choreagraphy. And, not the last, the young Mariah.
