Ahh, I could totally see it in Batman: TAS style, that would be gorgeous! Unfortunately cell animation is so unpopular for films these days (sigh~~~ - though they're getting good enough mimicking it with CGI, maybe it'll make a comeback! I like CGI well enough but not like I love cell animation...)

I absolutely loved RotG! Wreck-It Ralph is also delightful and very worth seeing. But RotG hit me right in the spot of my childhood adoration for those old Rankin-Bass claymation Christmas specials ^_^

(...and now I am looking up Rankin-Bass on wiki and confirming that no, I did not imagine up the special where this council of supernaturals was deciding whether to bestow immortality on Santa Claus...)
