I have had some problems with the motion control at times too, Marzy. Agree - boss in first temple was a frustrating time. Luckily didn't die, but certainly it was difficult.
Forget about the first boss once it's over - I haven't had too many problems after that. I think generally it's a case of you'll get used to it more over time. Hope you stick it out though.
I've also noticed just how dated and stiff Link's control movements are, and this is especially more noticeable having just played Uncharted 3 and loving the fluidity of it all. Different games, I know, but Link requires you to be extremely precise in his movements and grabbing of ladders, jumping onto ledges etc. 3D Zelda has always been like this, but it's certainly frustrating because you need to take that little extra time to do things. Trying to run up a ladder 3 times and instead running up the wall an inch next to it is annoying. Doesn't always happen, and it's one of those things you get used to, sure, but it does feel a little dated.
I've done 3rd dungeon now, same part as LKR I believe.
PS - do make sure others know what you have put in your spoilers guys. If it's after the 2nd dungeon, tell people that first, and then put your spoiler. Cheers
