Personally I don't agree with your opinion on a lot of things.

1. The Troll king healed Anna's head injury but you say that he also turned on Elsa and told her that her powers are dangerous. Yes, this is true, but the entire reason that they came to see the trolls is because of Elsa's lack of control. The Troll King was telling her that she needed to control her powers, which seemed to be the practical thing to do. A child with a great power is oen of the most dangerous things and for the King, locking Elsa away also seemed like the right thing to do for the protection of his family and his people as well as Elsa. Hiding her gift from Anna wasn't quite necessary but it made sure that she wasn't afraid of her older sister. What would you have done in the situation? Killed Elsa? Told everyone that she had magical powers so that people would fear her? I'd actually love to hear your explanation of what you would do if you were her father.

2. I don't think "Love Is An Open Door" is a villainous song at all. It was Hans trying to convince Anna that they really are in love. Maybe he does like her a lot but the song isn't foreshadowing or menacing at all, and it's actually my least favorite.

3. You failed to mention one of the cliches that are rampant in Disney movies: marrying someone that you've just met. I like that Disney turns away from this because it's just what they are expected to do with their stories. This movie is about showing the power of love in a different form, that love of a family can be just as true as a love with a mate.

4. Anna heads off alone to find her sister because I'm sure she's thought through what might happened and considers the fact Elsa is afraid and may hurt somebody if she thinks she's going to be forced back to the kingdom. Put yourself in Elsa's shoes. You've just revealed your powers over ice and the cold, and after running away your sister comes after you with a group of men. What are you going to think?
Also, it was sort of an idiot move for Anna to leave Hans in charge but she truly believed they were in love at this point. You have to remember that. She's naive and young and dumb, and she thinks that Hans will take care of everything for her. He does do a good job taking care of the people while she's gone and he even goes after her when Anna's horse comes back to Arendelle riderless. I'm sure he's assuming he will find her in the snow somewhere but regardless, he still plays the part of Prince Charming throughout the entire movie. There's nothing sinister about him until the end.

5. I don't think it's true that Kristoff and Anna have no chemistry. Maybe they have none romantically but their conversations flow fairly well and it's obvious that they have potential to be friends. The best of friends don't agree all the time and I think that's what makes them best friends because they know they don't share opinions on everything but still accept each other for who they are.

6. Kristoff's song about reindeer isn't supposed to be a main song. It's just him playing a mandolin and singing to Sven. That's all. I think it does show a lot of his character. First off, in listening to the song, one understands that Kristoff does not trust people. He thinks they're all selfish and only are out to serve themselves (like Hans, unbeknownst to the audience yet). But the second part of it subtly suggests that Kristoff does long to know people but I don't think he knows a way of interacting without without being social awkward. I mean, the audience doesn't know it yet but the kid was raised by trolls. How normal can you be in that situation? He even talks to his reindeer, which leads me into the other part of this section. His "conversation" with Sven about Anna dying in the woods? We all know that Kristoff wasn't going to let her go off alone to die in the woods. Sven is his moral compass in his mind and guides him in the right direction. It was his way of giving himself a logical reason to follow her. Also, the whole conversation about Kristoff antagonizing Anna about her quick marriage with Hans? That wasn't supposed to be subtle at all, obviously. When did Disney say they were being subtle about going against cliches? In all honesty, I think that it sounds like you just wanted to write about all the negative things of this movie and then you gave it a 7.5/10? From the way you describe it, it sounds like you should have given it a 2/10. I don't think you mentioned one good thing about it except that you liked Hans.

7. Personally I think the "In Summer" song was completely unnecessary. It did nothing for the movie and was basically a waste of time. I usually skip over it when I watch the movie because someone can do that and still understand the storyline without missing anything.

8. Seriously? The "Fixer Upper" song is a misunderstand on the trolls' part. They think that Kristoff has brought her to them because he wants to marry her and when he mentions she's engaged to someone else, they think it's a quick fix to just marry them outright right there. They think they are helping when it's obvious they're not. Kristoff and Anna quickly stomp this small flame of hope out for them when they inform the trolls that they are only there to see what can be done about Anna's condition.
Also? Your opinion on the "fixer-uppers" being dangerous? It sort of made me laugh. EVERYBODY is a fixer-upper, whether they want to admit it or not. We all have flaws that we need to continuously work on and better ourselves. Kristoff is a fixer-upper. Anna is a fixer-upper. You're a fixer-upper. I'm a fixer-upper. I like that the movie shows that people use "true love" as a weapon to get what they want via Hans. Also, it's true that Kristoff doesn't much like people but he wasn't going to let Anna die. Throughout the movie this becomes apparent because of what kind of person he is.
One thing that I liked about what you said is: "Little kids are going to grow up with this, thinking that the Fixer Upper man is the man to go for and nice guy, is going to murder your smurfing family." Sadly, this is actually what happens a lot in real life. The "fixer-upper" man is actually the guy to go for. Usually nice guys that you don't know are out to murder your "smurfing" family. Take Ted Bundy for example. He was handsome, suave and he seemed genuinely nice when women first met him and became interested in him. Do I need to say more?

9. "The trolls actually give good advice for once and mention that Anna can be cured by true loves kiss". Wrong. The grandfather troll says that an act of true love will break the curse and Anna assumes that he is talking about the love of a man. Back to the part where Disney is trying to show that family love is just as true as the love between a couple.

10. "Anna comes back frozen and cold, and Kristoff realizes that he has to give her up to Hans, leaving to a emotional moment, but Kristoff knew from the beginning that she already had a lover ? Why did he let himself fall in love and so quickly ? I guess emotions cannot be helped, but you would think that you could control a crush on a girl that you have just met, just a little more strongly son ??" Let's see...This guy has just gone on an adventure with this woman, risked his life to save her butt, she's saved his and you don't think there might be some chemistry there. Their feelings for each other were earned through their trials and eventual trust within each other.

11. I don't think it's disturbing at all that Hans is the real villain. Personally I think that regardless of the Fantasy elements, Frozen is the most "real" story that Disney gets. The characters actually seem like they are real people because that's how they would act. Anna isn't a lovely princess with flowing gowns and batting eyelashes. She's a complete dork, just like me, and I relate with her easily. She slips and trips and stuffs chocolate in her face. It's true originally Kristoff's intentions are just to serve himself but eventually he comes to like Anna. Elsa is just frightened of an uncontrollable power that she has. She's not some raging snow queen biotch that just wants to kill everyone because of their normal lives, like any other Disney "villain" would be.

Personally I think you focused a LOT on the negative parts of Frozen, even though you gave it a fairly high rating. I would suggest talking about the positive things more often.
