Wow, I don't know what was more impressive: the cutscene before the sixth dungeon's boss fight (just wait till you see it), or the boss fight itself. By far the best fight of the game so far - that was genuinely intense, which is something I don't normally say about Zelda boss fights!
Dungeon itself was okay. Not as good as the two before it though.
