Obviously this is aimed at kids, as is everything with the Clone Wars name (George Lucas would rather make a profit from kids party invitations with Anakin Skywalker's face on them, and I guess no one's going to argue with him), so don't expect anything challenging.
It's a very short game, around six different fights (however there are lots of challenges and different modes), and not a lot of characters. You are supposed to be able to do various different moves through swinging the Wiimote in a combination of different directions (left, left, up, right for example). First of all, the controls aren't sensitive enough to do these moves most of the time, it's blind luck if you get it right. Second of all, the moves all look pretty much the same so really you don't care if you get them right or not.
Half the fun comes from swinging the remote around blindly. Blocking is fairly pointless because it doesn't work half the time. You can't usually get a chance to use the Force either because your enemy can see it coming a mile away. BUT it is fun to play, and a very good workout! It's great in multiplayer after a few drinks.
To those complaining about the repetitive dialogue...you do know you can switch it off in the options menu, right? Only takes a second.
It's not the lightsaber game we've all been waiting for. If you've played the swordfighting games in Wii Sports Resort you'll know that the technology now exists for a great lightsaber game with sensitive controls, so hopefully there'll be a decent one in the future.
