Aside from Navi hollering 'Hey!' and saying the same things one too many times, one of the things that annoy me is I try to turn away from a wall, then the camera changes too quickly and I get lost, then I end up getting killed by a mini/boss/ boss. Maybe that's just me, LOL xD
And omg, I can totally relate to you, about repeating the introduction and instructions before errands and missions. So annoying e_e;
