Elsa Should Have Fallen
Frozen would have ended very abruptly (and would have been less child friendly), had Elsa just fallen off this cliff as she logically should have.
In the beginning of the forever iconic Let It Go, we se that Elsa is walking over flat, snow-filled ground, and is around 30 feet from a steep edge.
When she starts running, she should quickly reach it and fall off. Instead, she’s suddenly running up a hill that was never there before, and from that hill she creates ice steps that bridge the gap.
