Disney still has much to do to wrap up the series with Frozen 3. The first and second Frozen films, released in 2013 and 2019 respectively, followed two royal sisters in the kingdom of Arendelle. The eldest, Elsa (Idina Menzel), was raised to one day become queen while also doing her best to hide her growing ice powers from the world. Her younger sister, Anna (Kristen Bell), struggled to grow up alone after the death of her and Elsa's parents. Frozen explored their reconciliation after years apart while Elsa also learned to accept her powers as something to be celebrated instead of feared.

The sequel Frozen 2 expanded the sisters' world with the introduction of the elemental spirits, which were angry due to an old feud between the sisters' grandfather and the people of Northuldra. Once more, Elsa came to terms with the extent of her abilities as she tried to heal this old wound. At the same time, Anna did her best to support her sister and help the Northuldra people. The sequel ended with Elsa abdicating the throne in favor of her sister in order to better embrace her new role as the Fifth Spirit — the bridge between humans and spirits.

While a third Frozen film has not been officially announced, the success of the first two movies makes another possible. Fans have speculated ever since Frozen 2's release what a continuation of the franchise could mean for the characters. Here's everything that still needs to happen for Disney to end the franchise.

Frozen 3 Needs Better Worldbuilding

The Frozen franchise has still not properly explained the existence and properties of magic. The first Frozen had framed Elsa's ice powers as unique: The people of Arendelle were initially afraid of her abilities because they had never seen anything like them before. However, the sequel introduced new lands where magic was a part of daily life. Northuldrans were already familiar with different types of elemental magic. They had never seen Elsa's particular brand of magic before, but they were not fearful of magic like the people of Arendelle used to be. Elsa and Anna's grandfather was particularly distrustful of magic, leading to his tragic betrayal of Northuldra, but neither film provided any sort of context for this fear. Perhaps they simply did not support something they could not fully understand or maybe there was a more specific reason for the animosity.

Neither film explained the existence of mythical beings like the Rock Trolls either. If some people were frightened by a person wielding magical powers, why weren't they also afraid of the existence of magical beings? While the Earth Giants seemed generally feared, the Rock Trolls certainly were not. Elsa and Anna's parents visited them in the first movie, implying they were known about and accepted. However, this doesn't fit with the aggressive stance against magic users. Frozen 2 also did not delve too deeply into the spirits' roles in society, leaving much information about them unexplored.

Explain Elsa's Powers & Origin

Although at first glance Elsa simply has ice-themed powers, the movies repeatedly expand what she is capable of doing with her magic. Throughout the franchise, Elsa had created living snow beings, magicked new clothes for herself, and sent memories to a specific person in an unknown location. These abilities are obviously much more complex than just ice powers, and in some instances, are completely unrelated. Frozen 2 needs to explain what exactly are the limitations on Elsa's powers, and diving deeper into the meaning of her role as the Fifth Spirit might help.

Frozen 2 ended with the revelation that Elsa is the Fifth Spirit and meant to serve as the bridge between humans and spirits. She explained to Anna that together they can connect the worlds of humans and spirits. The movie did not really say much more about it than that, or really explain what being the Fifth Spirit entailed. It was also unclear if the Fifth Spirit was a title passed down from person or person, or if her heritage, having one parent from Arendelle and one from Northuldra, had something to do with Elsa becoming the Fifth Spirit. It also seemed to be part of the reason Elsa survived her brush with death, which begs the question: Does being the Fifth Spirit mean Elsa is not actually human at all?

Clarify Elsa's Relationship Status Or Lack Thereof

Ever since the first Frozen film, fans have simultaneously praised and questioned Elsa's single status. Disney princess films are known for their romantic love stories, and while Anna has had a heartwarming romance throughout the films, Elsa has remained single. Many viewers have applauded this choice as a way for Disney to show young girls that romantic relationships are not necessarily the most important aspect of a person's life. Yet, others have repeatedly questioned when, and if, she will ever meet someone. Some fans latched onto Elsa's brief interactions with Honeymaren in Frozen 2 as a potential love interest for her, clamoring for the possibility of Elsa as a lesbian Disney princess. Regardless of the direction in which Disney chooses to take her love life, they must make a choice to end the speculation.

Let Anna Stand Alone

Throughout the Frozen franchise, Anna has primarily existed in Elsa's shadow. Although Anna has had opportunities to grow as a person and make her own choices, those choices have mainly been in support of her sister. She rarely has had the chance to just do things for her and her alone. While it is obviously important for her to care so deeply for her sister and worry about her, Anna also needs to worry about herself. She is a dynamic character all on her own, and it is about time the story reflected that. Hopefully, if Frozen 3 is ever made, it will be able to devote time to these issues to create a truly compelling finale to a fun and successful franchise.
