Ganondorf in Twilight Princess was way too long and drawn-out to be any good. And hour-long climax is not a climax, it's just exhausting overkill. Three phases should be THE limit.
But in the context of Twilight Princess it was perfect. That boss fight, and the game itself, are the word "epic" in game form. An empty shell of epic epicness that ultimately doesn't mean anything and has no substance inside. An homage to superficiality. I can't say enough bad things about Twilight Princess if you disagree with me just ignore it and we can still be friends
