Bratz: The Movie isn't complicated to play at all, really. The controls are mega simple and easy to understand and implement. When walking around the compound, you use the D-pad to walk around and hold down on the (B) button to "dash." Each of the mini-games have different controls, but none of them (with the exception of the balancing game) are overly complicated. Most of the time, you use the D-pad for control and the (A) button is the action button. On occasion, you only use the D-pad (for the sewing game, for example), or, as with the balancing game, you use all the buttons including the D-pad.
There is no saving in Bratz: The Movie, but they do give you a six digit code that you can enter in at the start-up of a game to get to the point where you left off. This... is annoying. The code is entered in through the up and down arrows on the D-pad, and cycles through the alphabet twice (capitalized and lower case), numbers 0-9, and some random symbols. If you mess the code up, you have to backspace to the point you made your mistake and consequently delete every entry you've made... this is also annoying. Memorizing the code, or finding a pen to write it down is also so obnoxious.
For a twenty-five-year-old, Bratz: The Movie might not be the most exciting game in the world, but if you are stuck in a college class or a doctor's office, it is a good way to pass the time. The music and the map are the biggest downfalls of the game, but aren't enough to destroy the more entertaining aspects. Definitely rentable if you've got pre-teens in your house.
