Frozen Plot Holes You Can't Ignore

From Redditoru/Guild_Navigator:

Foreign dignitaries assembled when Hans tells his story about Elsa lack power to recognize him as heir. Hans is a foreigner in a realm that isn't his.

From Redditoru/namhob:

The trolls state only an act of true love can save Anna.

Before the main scene, Olaf lights a fire for Anna in the castle. Anna warns him against it for clear reasons. Olaf lights the fire anyway, thus risking his own life to save her.

Does this count as true love?

From Redditoru/garfangle:

Elsa became the heir apparent when the King and Queen died. Before her coronation, someone needed to rule the kingdom until she reached age twenty-one.

Why would Anna give the kingdom to Hans, whom she just met, if a capable regent exists? Also, why would the townsfolk trust Hans, and only slightly, theDuke of Weselton, to bring Elsa back? Is there no one else who can give orders?

From Redditoru/Guild_Navigator:

Hans tells everyone the princess is dead; no one checks for a corpse. I get the need to speed up the plot, but this feels like bad common sense.

From Redditoru/TheGifGoddess:

How did Arendelle's people know Hans was the bad guy? They cheered when Anna hit him, but Hans acted as a helper, giving blankets, seeking the princess, and trying to save Anna. Diplomats saw Hans about to kill Elsa with a sword, but they already knew he would sentence her to death.

[Also,] why were they standing on a balcony in a snowstorm?

From Redditoru/mikayce:

Takes Anna and Kristoff—who knows the terrain—two days to reach the North Mountain.getto the North Mountain.

Takes Hans—who doesn't know the terrain—about one day to travel to the North Mountain.andreturn.

From Redditoru/MistrMink:

Elsa is the only one thinking clearly in her family; she is dangerous. Her power exceeded her control, making her a threat to everyone. Three times she used her power in Anna's presence, two times Anna almost died.

[The whole] - "She's my sister, she's not dangerous," [that idea is silly]. How could you possibly know that? You have barely seen her in ten years. The "act of love saves the world thing" lacks reality. Nothing changes by the end; Elsa remains a threat, no matter if she suddenly "found love." She froze the whole ocean! What will you do if she suddenly [does something similar] just because she feels emotional?

From Redditoru/ParrotDrumStickBitch:

Elsa had almost no control over her powers for the first 18 to 20 years of her life, but she could build a castle in minutes with zero practice.

From a former Redditoru/[deleted]:

[Kristoff] buys carrots and stuff, then gets thrown out by the guy for calling him a thief. He tells his reindeer, "But I have good news, I found a place to stay, and it's free!" Where did that come from? The place sits about 30 feet from the giant guy who threw him out, and he has a fire going. He is squatting in this empty house while Oaken is right there and that family in the hot tub probably won't stay all night.

From a Redditoru/kromagnon:

Elsa faces a crossbow shot. Hans moves the weapon out of the way to save her life.

Why? WHY?

This is the chance he waited for. He has Anna's love. Elsa blocks him from being king. Hans should have let Elsa die by crossbow and married Anna later, or faked it, just like he did.

This plot hole is more than a dumb decision. Hans is not dumb. He plays the hero role to gain trust and makes Anna love him [he convinces the audience]. The writers let Elsa go for a big plot twist.

From a Redditoru/Soyyos:

Elsa wears gloves because they help her control her powers. Yet, she creates ice with her feet through her shoes. How does the glove fabric stop it, but the shoes do not?

From a former Redditoru/[deleted]:

I thought Elsa and Anna stayed locked in that palace for years, never seeing the outside world. But when Elsa runs, Anna calls for her horse and rides away confidently. Where and when did she learn to ride?

From a Redditoru/Thirteen_Fears:

Sven is about Kristoff's age, and Kristoff is about Anna's age. They are kids when first seen. So, Sven is 18 when we see him during the movie.

[One problem] - male reindeer are expected to live just over 10 years.

He seems lively in the movie, so they must have overlooked this in favor of giving Kristoff a best friend.

From a former Redditoru/[deleted]:

[How were there] normal-looking ships completely submerged while many others rested above the ice.

From a Redditoru/Jeremy-Hillary-Boob:

When Elsa, Anna, and their parents visited the Trolls, Kristoff and Sven were present. [It was clear who the family was] and how important they were.

Later, Kristoff sees Elsa and Anna but never mentions their first meeting.
