This is pretty daunting at first, and the learning curve is awfully steep for an hour or so - mostly because you'll have to keep a little cursor projected by the remote onscreen if you want to do more than punch. Dashing and flying, both done by shaking the Nunchuk, also take some getting used to, and then they only seem to work right half the time. Once you get the hang of that, though, the controls start to feel natural, and they actually become more fun than a traditional setup.
What makes using the remote especially cool is the way it handles super moves. Regular old punching and energy attacks are handled using the A button and B trigger, but to perform the really big, world-ending techniques the series is known for, you'll have to perform movements that are slightly different for each character (which helps make them feel less same-y).
