Its controls are a little ropy and its depth severely lacking, but these aren't concerns that will trouble the audience it's aimed at. Not only that, but it's tremendous entertainment value. Just ask my other half. She hasn't laughed this much in ages.
Overall, this game does what it says it will on the outside of the box but with limited gameplay modes and a scant song selection, you might want to look at renting it first before you make a full purchase.
