Looking at this audience, it's actually absolutely weird we don't have a thread on this yet.
It's out already, obviously, and has been since Thanksgiving.
I absolutely loved it. Hands down wins my #1 spot as Best Disney Princess Movie ever, shoving tangled out of that spot.
It has one of the best songs since the Lion King. Tangled had When Will My Life Begin, Mother Knows Best and I've got a Dream, but frankly, Let It Go, both the song and the scene blow those out of the water.
Actual Scene Video (More spoilery)
My only real con for this movie was that some of the singing was just unnecessary, but thankfully weren't belabored to death and it didn't continue a theme through the whole movie.
