This goes without saying, but I'll say it. Demise's battle bore the most epic feel out of any other final showdown. That goes especially for the latterly phase, when he triggered the storm, hoping to utilize the energy of the lightning to his own advantage. Instead Link picked up his maneuver and began employing it against Demise, while emphasis remained very much on the Master Sword. After all, this was the origin story of the Blade of Evil's Bane, and the focus remained consistent upon just that. Coupled with the motion controls, nothing caused that to differ, not even the last skirmish. The Master Sword clashed against its anti, against its opponent, not it proved full well that indeed it would be a detriment to everything encompassed by wickedness, and that is very true considering that evil supposedly stemmed from Demise.
