Water Temple as a whole isn't so bad, just the damn Dark Link mini boss fight. Dunno if they made that easier in OoT 3D, but I remember it being hella difficult in the original game without getting a bunch of magic potions and spamming Din's Fire.
I need to play through it again and see if I can do it another way.
