I FINALLY saw this last weekend. (I know, I'm way late to the party.

) I thought it was beautiful. I started weeping during "Do You Want to Build a Snowman?" and got myself under control just in time to do it again during "The First Time in Forever" so that by the time "Let It Go" came along, I was a mess.
If you love the music, do yourself a favor and check out the deluxe 2-disc soundtrack. It includes several songs that were cut that are also pretty great. I can see why they were cut, but they're a lot of fun and add character depth.
I was shocked and sad that Hans ended up being EEEEEVIL. I would have liked it better if he had been a decent guy and just wrong for Anna. The fact that he's so horrible casts a shadow over "Love Is an Open Door", which I really love.
And I admit I find Idina Menzel a little distracting, especially during "Let It Go", because all I hear is Elphaba. It doesn't help that the characters are so close in motivation. I mean, "Let It Go" is basically "Defying Gravity, Disney Version."
But yeah, I haven't thought about much else since seeing the movie. There's a whole lot of interesting trivia in the IMDB entry. The guy who voiced Olaf ad-libbed a lot of the funny lines. OH, and I can't believe no one mentioned the post-credits easter egg! Marshmallow finds Elsa's discarded crown and puts it on himself, then grins at the "camera." It's adorable!
ETA: Oh, and to the point that Anna has freckles, if you look close, Elsa does too, although they are more subtle.
