On the way to Rise of the Guardians, I noted that, between Santa Claus and the Easter Bunny, the two most important days in the Christian year were covered by members of the titular Guardians. I said I'd bet that Jesus would not be mentioned once during the course of the movie, despite this. My brother took me up on this bet.
My brother owes me a coke.
This movie is explicitly about believing in things we have no proof of (like, I don’t know, Jesus); the Guardians, we're told, are powerless unless the children of the world believe in them. Strangely, I don't remember ever believing in the Sandman, the Easter Bunny or even, yes, Santa Claus. Maybe I did; but I don’t remember it.
The closest I came to believing in any of the Guardians was the Tooth Fairy; I don’t remember actually believing, but I do remember being very disappointed upon finding a tooth that my parents hadn't yet discarded after trading for a quarter.
Speaking of disappointment, Rise of the Guardians was a letdown.
