I too have never had any troubles with the wiimote that couldn't be solved by reading the manual.
Neither has my remote been so laggy as to make a game less enjoyable.
I also agree that Red Steel could have had better controls, but to be fair, what do you expect, it's from Ubisoft (as you can tell, I'm not a great fan). It was an 'experiment' to begin with, one that has spawned off the upcoming Red Steel 2 (working title), that will hopefully iron out all the bugs and the like.
But ye, the wiimote is really very good and versatile.
