The cheerleaders are all happy and perky and I don't find the controls difficult at all! The only thing is that in one song it says a couple of words which I did not expect, but it isn't a big deal to me.
I reccomend this game for ages 12 and up because (1) the lyrics have some bad words (2) a couple songs have provocative dance moves and (3) the controls are hard to get use to. It does have party mode games and an exercise mode. The exercise mode makes me work up a sweat. Overall this is a pretty good game.
