I'll also add that some of the gesturing is really good.
The only ones I don't like are the rocket launcher and melee. You have to flip the control back, so the IR is facing away from the screen, like you picked up the bazooka and put it on your shoulder. That puts it into aim mode. The weird thing is, you have to aim with the stick, which is different than everything else. It just seems inconsistent.
The melee gesture responds very well, and is pretty effective. You have to thrust forward with both the remote and nunchuck. The problem is, I always end up pointing the IR away from the screen, so I end up looking at the ground or air when my attack finishes.
Some good gesturing, that's very simple, is the sniper rifle. You twist the wiimote like you're turning a dial to zoom in and out. You can press the C button to luck and unlock the zoom. With all of the weapons you can lean while in aim mode by tilting the nunchuck. So, you can aim, lean, walk and zoom all at the same time without even a thought.
Planting explosives works pretty well. You twist the wiimote like you're turning a dial to set the timer, and then pull up on the wiimote to set the charge.
There was a little thing where I had to tune a radio, which seemed overly sensitive, but probably because I've cranked all the sensitivities up way past their default. Still works well.
