Bad things;
- Disney tried to get out of their little box of main hero x main heroine, but it wasn't that successful. According to the timeline and Olaf's age, Anna and Kristoff only spent a day with eachother. Even though they went on an epic journey together, they just met eachother, just like Anna and Hans.
- If they're gonna put them together in the first place, I would've liked to see some hints that Anna is falling in love with Kristoff. She only thinks of him in a romantic light after Olaf pulls a Sai and tells her that Kristoff loves her. Even before Sai told Sakura, there were plenty of hints from her. I don't really hate this cliché, I just think it's hypocritical how Disney tried to debunk it and failed.
- The parents.

They had their heart in the right place, but their actions were wrong. I wish that could've been acknowledged.´
- Not my idea, but repeat of "Let it Go" at the end would've been a great way to show that song in a positive light. First time we heard it, it was about letting go of all the fears by escaping. It was the wrong way, and it would be great to show the right way at the end.
- The sisters' relationship could've been written much better. They hadn't seen eachother since they were toddlers, suddenly they're besties again. It was a bit too easy.
- While Disney made a very accurate adaptation of Norwegian culture, what they took from Saami culture was very inacurrate. It disappointed me how they could research one culture so deeply, and misrepresent the other. I don't know that much about saami people, but I noticed something was off. Like how Kristoff's sleigh looks way too upper-class.

But I made some research, and
this post, written by a saami, explains it better than I could.
- The trolls song perpetuates the nice guy trope.
That's not all probably, just things I can come up with now. I'm really not a LAP-poster either.
I don't think the movie is bad, I just wouldn't rate it 10/10 anymore. It's very overrated. It isn't a movie I would watch over and over again, but it is enjoyable a few times.
I really agree with the IMDB rating, 7,8. I wouldn't put it below 7,5 because the movie has excellent animation, soundtrack, voice acting, etc. The opening song "Vuelie" is also one of my favourite Norwegian classic instrumental songs!
I really like Anna's character(and her dresses, I want to wear them!), she's very quirky and doesn't lack personality, and unlike the other princesses she doesn't wake up with perfect hair. The Oaken character was great too. I'm also glad that at the end, the sisterly love was what broke the spell.
