I played the crap out of the Wii TP, and I thought it was fantastic. The "waggle" motion became as routine as pressing a button to swing, really, and I had absolutely no problems with it. Plus they were pretty amazing for the fishing minigame, which I also played the crap out of. Maybe the wiggling was shoehorned in on the combat side of things, but I thought it worked out fine and was a bit more involving and immersive than just slapping "A".
Seriously, people deciding to not play the game because they don't want to flick their wrist around lazily instead of pushing a button lazily is pretty weaksauce.
