What a crap control scheme. The inability to test your controls as you adjust them, forcing you to go back and forth thru the menus, only adds to the frustration.
Acknowledging the inaccuracy of "aiming from the hip" with a large reticule bubble is appropriate for handicapped controls schemes like mouse and double-anal that are meant to be hindered, but this is the 3rd time in a row that Treyarch doesn't recognize there's inherent instability in aiming with the Wii Remote, yet the reticule bubble is still huge instead of depending on the Wii Player's own steadiness. Oh, then there's the idea that aiming from the hip isn't useful to professional soldiers, and shouldn't be in this type of game AT ALL.
Scoped view, typically with Reflex Dot Sights, should be the default view for general movement, but the game messes that up, like the last game, with its god-awful stuck-in-place Call of Rubberband effect. And the fact that you see way too much of the gun on the screen as it moves around (when your eyes would be close to the eyepiece instead) makes it look stupid and awkward.
So all the shitty functionality really lets the control "options" go to waste.
