I really did like Zant, he had character development, and was different from most other Zelda villains. He was a nice change, as to me Gannondorf/Ganon is a plain villain, but can still be liked. Zant was really awesome in the beginning, and throughout the game, all his plans, all his dreams, everything he wanted, he got, then some random kid/wolf-demon guy (link) shows up with Midna, and ruins everything. Suddenly his grasp on power and the whole Twili race is falling apart, so he goes crazy, and I personally thought the water phase was hard. Kept yelling at the TV: Come over here Zant! Over there? No.. COME ON. SHOW UP ALREADY. I also liked the whole re-cap boss fight, going through multiple boss arenas. I personally think GANNONDORF was the weaker villain in the whole game, the Zant fight seemed final boss-ish, then you have the Gannondorf fight. Gannondorf is just plopped down as the main villain behind all of this after Stallord (Who probably lots of people will agree with me as my favorite TP boss, Zant being 2nd), felt... Lame. In the end, you have him finish what he started and make the world right. He might not be original for villain, but he was awesome for Zelda. All hail the Usurper king!
And how come nobody hates Majora's incarnation because she acted like a fool!
P.S: This. This is true. Very true.
