I thought he was boring as a villain. Just another spoiled prince, bored with life, yada yada. I would much rather have had Yotsuyu as the main antagonist this expac. She was complex, had an elaborate and interesting backstory, was crazy and hell and just plain evil, yet you sympathized with her due to the cruelty she had to endure and you could understand what drove her to hate everyone around her so much. They could have done so much more with her storyline and character with the complexity they had already given her. The focus on Yotsuyu is what made 4.3 one of the best story patches to date in this game.

There is nothing to sympathize with or special about Zenos and his character is very one dimensional. He is just another yawn-worthy, emo villain with a big sword which is a all too common and much overused character type in the FF series already.
