Now, I must admit to being something of a Disney fan. I pre-ordered this on Blu-Ray and it arrived yesterday.
I am not sure what I was expecting from this, but it wasn't quite what the trailer with the Snowman and Reindeer led me to expect! That's not to say I didn't enjoy the movie, though I think that Tangled is still my favourite (I have that on Blu-Ray as well!). There was a lot more singing that there was in Tangled. I think the Reindeer was the new Maximus (preferred Maximus in Tangled, as he was superb).
Based (loosely?) on the "Snow Queen". I do have the fairly recent mini-series of that on DVD.
On High Definition the picture was of course superb (as it should be on a recent release). I only watched it through the TV so far, which meant I only had the sound in stereo. Will have to watch it again utilizing my mini 5.1 surround system.
There seems a decent amount of extras, though I have yet to check them out.
