I spent a good 5 hours playing this game last night. By far, the BEST thing on the Wii. It's a normal game, the controllers movement doesn't affect the game play at all (least it doesn't in the setup I used), but it doesn't affect the game at all. The Campaign is awesome. It's not just fighting, there is levels that you go through, and video stories that pop up between levels and fights.
I HIGHLY recommend this game to anyone with a Wii.
