The Wii lightsabering is a bit hit and miss. You just wave it, left to right, right to left, up and down, + push forward to lunge. No fancy jedi saber twirling unfortunately. Its quite hard to get the waving right to create combos though.
However, using the nunchuck to control the force is excellent. Thrust it forward to do force push. Use one of the buttons to grab, then lift the nunchuck to lift the item higher, then use the joystick to launch it. Force grab someone then twist the nunchuck to choke them. Charge up repulse or maelstrom with the buttons then flick the nuchuck and wii-mote down to unleash it.
It almost feels like doing the force gestures in the films.
And more than compensates for the merely adequete lightsabering.
