To each his own...
To me, it made me stay away from Nintendo for a gen (I'm back with the Wii U).
Motion controls never did it for me, sans Wario Ware Smooth Moves (that one is indeed a gem).
But I disliked Metroid Other M, Skyward Sword, and the Wii Mario Kart.
Also, TP was better on GC, just sayin'
And DKCR was better on 3DS because you didn't have to waggle the controller. That really killed the game for me.
DK:TF on the other hand, godly.
Anyway, I don't think the console is crap or bad, not at all, and I understand its cultural legacy/impact.
But I prefer NES, SNES, N64, GC, WiiU over it.
