The second series of the frozen.
In my opinion, the second series is usually low quality than the first one but this one was not like that, and after watching this, I thought that it may keep going to another movie.
This bailed out the story of their parents, their roots.
The ending was why I thought this may keep going because the parting each other and showing their ways.
This may be a bit difficult for children to understand the story but visually enjoyable.
