Sure, Frozen is a lovely tale about sisterhood and love...but it really didn't have to go down like it did in the movie.
Elsa didn't need to be secluded from everyone, she didn't need to hide her powers! Had the movie actually embraced Elsa's powers the entire way through, then the movie might've looked a bit like this bit by How It Should Have Ended.
Frozen probably wouldn't have been as poignant with this new premise, though—that's the trade-off.
