All I know is I do some work for a bunch of Disney and Pixar employees and they are all lilberal fruit cakes, almost without exception.
Mark Henn, a 30 year Disney veteran who worked on this movie had this to say:
“Christian families can use [Frozen] to talk to their kids ultimately [about] honest, sacrificial love. We all understand that. The love of Christ is sacrificing His life because He loved us so much. God so loved the world through Christ. That’s sacrificial love. Those are elements that, while not so blatantly, “here’s a Christian message”, but they’re there. For Christian families in particular, they can just peel back the layers a little bit and then be willing to, as parents, talk to their kids and just have conversations about that.”
