We saw it this past Friday, and I didn't enjoy it at all.
I thought it was unoriginal. It was literally just the movie on ice. I thought there would be more narration from Mickey and interaction with other characters. Maybe mickey telling the story as they went from song to song. I don't know, just didn't seem original to me to just use the dialogue from the movie to tell the story.
We have seen disney on ice twice, both times I think it was the 100 years of disney show and I liked the way they included everything. I realize this specifically was Frozen on ice, so maybe I went into it with false expectations, but like I said, I just wasn't that impressed. It was just audio from the movie playing while they were skating.
Thought it could have been done better, but my 3 year old enjoyed it and seeing the look on her face made it worthwhile for me.
