I just beat the game and it was pretty freakin sweet! Some of the early levels are sorta tedious as you earn "points" so that you can upgrad your force powers but after that you get some pretty cool ones like detonate (push em back into their group and send an explosive ball into them. they explode taking their group with them) to Pummel (grab a guy and hold him in the air, swing the wiimote and all sorts of solid objects, including his fellow troopers, fly into him and crush him) to the eversweet Lightning (bzzt). some of the controls take a bit to master but that's ok, the basic moves are strong enough throughout that you aren't without tools.
The bosses are challanging and usually pretty unique. if a bit repetitive but that's sort of the nature of games. there are even some regular troops that will be able to block your saber and cause you pain. the big massive lightinging is your friend. ;)
one of the bigger problems was being able to grab the right item, but that just took a bit practice to get used to.
overall I give it a 9 out of 10. lots of fun but fairly short and the lightsaber controls leave a tad to be desired.
Note; I was playing on the Wii. I heard the PS3 didn't have a good chunk of the force powers.
