Not so great execution. "Wii Fit" attempts to turn your Wii system into a full-blown gym. The concept of a video game exercise program has a LOT of potential, and I think we'll be seeing a lot more of these types of games in the future. But, as for right now... this doesn't really work. The BMI scale ratings in this game are just absurd (an anorexic person is called "obese", for example), the motion sensors aren't always responsive and can be quite frustrating, and, worst of all, the game just isn't that fun. There are a few fun minigames in "Wii Fit", but many of the games are just drab and boring. "Wii Fit" is an interesting experiment, but that's probably the best thing about it: it's an experiment. An experiment with a lot of potential. (Contains no objectionable content.)
