I say good. I don't like all this "flappy flaily" wii-mote controls nor particularly what PS-motion/Natal seem to be offering. A gamepad can give much more "certain" results and face it, it's not like you ever actually felt like you were wilding a sword as you flail the white plastic remote in the vain attempt at trying to activate an attack animation.
I tried Twilight Princess on Wii and played through to completion on Gamecube and honestly prefer the game-pad controlled Gamecube version. I understand most people play Super Smash Bros Brawl with a gamepad as well.
That's because Twilight Princess on the Wii was a direct port with motion controls tacked on. This is the other way around.
Honestly, NMH is one of the only two games on the Wii that I felt benefited from the motion controls. They were subtle enough to not become irritating, unlike Twilight Princess's "Why the hell did you slash twice, Link?" play. Also, in my opinion, that extra slash to finish off an enemy felt very satisfying, in that slow motion "Batman kicks a thug in the face" way. By the way, yes, I did at least somewhat feel like I was wielding a beam katana. Moreso than other Wii games that happen to have swordplay somewhere in the mix.
You also don't "flail the remote" to trigger an attack animation. Did you ever actually play this game?
