It looks okay. The backflips should be fine on the nunchuck, and the advanced punches will probably be waggling. It's always hard for games like this to do well control wise, since there's only really two buttons instead of your average four (once you take away the nunchuck which is mostly used for misc. control). Basically, it has to use motion controls to make up for the lack of two buttons.
