With Frozen 3 confirmed by Disney, fans are wondering who the third film will revolve around, and truthfully, if the movie is about Kristoff, it will be ruining what has made the franchise so great in the first place. Disney's Frozen was first released in 2013 to incredible acclaim by both audiences and critics. A sequel, Frozen 2, came out in 2019. Frozen follows princesses and sisters Anna and Elsa who are torn apart by Elsa's ice powers, but ultimately learn to love and accept each other and themselves.
