honestly i didn't like frozen that much
it's a kids movie, so they clearly focused more on the visuals and "humor" more than the actual plot, but I felt like it was massively lacking in actual story
[Spoilers, highlight to reveal]
it was never explained how she got the frozen powers in the first place, and if she had already nearly killed her sister as a child with the Frozen power, she should've learned to be more careful and NOT DO IT A SECOND TIME. There are more plotholes that I'm not going into detail about here.
[Spoilers]
Overall, the plot seemed very week.
