While the controls are unique and innovative, it simply cannot match up to the other options you have.
It takes a loooong time to get used to the controls. While they can be a bit frustrating at first, in some areas, you definitely feel into the game.
Chucking grenades is a bit frustrating since any slight move of the controller (and you'll have to adjust your grip to throw the grenade in the first place) can send your aim off in places you don't want it to go.
Planting charges is fun; you actually follow a series of motions to set it in the first place, giving a more realistic feel to the game.
Overall, for the Wii, it's highly recommended. However, the lack of multiplayer and online is frustrating, especially for a console that should've had some online compatability by now. if you have any current-gen consoles or the 360, try them instead.
