Make some soup and cocoa and prepare to curl up with your little princesses for this flick, especially in winter. Elsa and Anna have a great, realistic sisterly relationship anybody with siblings can relate to. Discussion fodder exists in the form of Elsa's ice powers, why she fears this, and what they help teach her about love. Families can also talk about Anna's reactions to Elsa, her engagement to Hans, and why it was so easy for the villain to deceive her. Appearance vs. reality and the mix of beauty and danger are big themes here.
Minor caveats exist. Elsa creates and employs a potentially scary abominable snow monster, and her powers themselves may scare younger viewers. The villain's actions are particularly underhanded for a Disney film; Anna responds by punching him. Sentient snowman Olaf makes a reference to yellow snow, and references are made to hero Kristoff liking to "tinkle in the woods" and smelling bad, as well as having a relationship with a pet reindeer that's "a little outside of nature's laws." Overall, though, this is a truly pleasurable frozen treat with plenty of warm family-friendly morsels.
