This is a great, 4-star musical production for just about all ages, but I have a couple of nitpicks about the review. First, it states that Jonathan Groff was the voice of Olaf, when, in fact, that character was voiced by Josh Gad; Jonathan Groff was the voice of Kristoff.
Second, the review fails to mention Christophe Beck's original score for the film, which makes up about 3/5 of this 70-minute CD. It's really quite rich and lovely, but it could be boring for children or for people who dislike wordless backround music. Also, some parts of Beck's score are suspenseful, dramatic, or mildly scary ("Marshmallow Attack!" and "Summit Siege," among others), so extremely sensitive children MIGHT be scared by it, but only if they're really sensitive. However, there aren't any bad lyrics in the songs or score, so there's nothing inappropriate on this CD.
