From IGN.com's review:
"Traveller's Tales got the game's Wii controls right, a feat not all developers - especially of multiplatform licensed games - can claim. You can either use the Wiimote like a traditional controller, pressing the B button to swing your lightsaber, or you can swing the Wii remote to strike.
You don't have to turn it on or off - it's there if you like it, and you can ignore it if you don't. The game also makes refreshingly great use of the Wii remote's speaker to deliver a spot-on lightsaber hum.
Gameplay: overall the game is easy to control and fun to play"
