My daughter is a little like the kids in this light article by Kevin Noble Maillard:

What’s the most accurate way to describe kids’ relationship to “Frozen”? Adoration is insufficient, and obsession is downright weak. It’s more like a cathexis, an acutely intense energy focused on a singular entity.

My daughter was borderline obsessed with Frozen for about five years. It lulled a bit for a while, but the existence of “Frozen II” on the horizon has revived her enthusiasm, especially with Elsa, quite a bit this year. After months of looking forward to it, my wife and I are taking her to see the sequel this weekend.
