Loved that they flipped the "true love" thing around and instead of a kiss, it was sisterly love. I thought that was really sweet to do.

It was also interesting that it really didn't feel like there was a big bad villain for most of the movie up until the end. I like the other conflicts they had in this taking focus, and even the old fellow who wanted his men to kill Elsa seemed to be very minor.

The Kristoff/Sven stuff was also really cute and sweet; I didn't even realize at the beginning he was alone, I had assumed the other men cutting ice were family. The little rock trolls were cute.

Except for "Let it Go" I didn't care much for the other songs. That said, Let it Go is really great. I've listened to it a bunch today, both the scene from the movie and the Demi Lovato one (which I heard on TV this morning from Disney World's event.

I wish the animation was a bit more unique, as it looked a lot like Tangled and nothing particularly new or interesting. It's nothing bad, but wish it had a little more charm to it.

The only other real complaint is Olaf, which I still didn't care much for. Wish he was played more straight and not slapstick.

1. Sadly, parents don't know everything, and can react in ways that may not help.
2. FEAR was the villain in this movie. And while the trolls made that clear, what was unsaid was that it was her fear that was the biggest enemy, followed by that of her loved ones... and only then the fear of the normal people.
3. It's all allegorical (potentially for MANY things). "Conceal, don't feel" is surely only a tiny step away from "don't ask, don't tell" for one, but then you also have "growing up," "gifted (double meaning required) children", undertones of racial prejudice, and a more general "being different" (including 'privileged up-bringing' and the more-rarefied - and or mostly-fictional - 'destined for greatness'/subject of a prophecy)
4. Mentors or parents or friends or teachers who do not have a particular skill are rarely the people best equipped to teach or coach, but often those thrust into that role. The choice may be between muddling through or shipping a 'gifted' child off on their own. In Frozen elements of both were used: doing what they felt best and sectioning her off in a 'class of her own'.
