I recently bought this game, and this is what I thought.
The controls are impossible, aiming can be a problem, and the wiimote can sometimes feel very sensative, and I feel like im somewhat playing metroid DS except the controls are much harder.
The gameplay is intense though, Nintendo kind of wanted to let the Wii be fun for everyone one, and they also wanted to let you feel like you are in the game, well for this one. I guess your imagination must run wild, cause it can really intense, and it more fun that way ;)
Overall, the game may be worth buying if you are a fan of the CoD series. This game can go into the catagory "buy next time" If there is another game you want, buy that game then get this, you wont miss much.
I give this game a 7.5/10
