An irredeemable evil villain can be fun at times. I like Kefka, the Emperor from Star Wars etc. But Zenos just never had any appeal for me. Not every villain needs a sympathetic motive, but he never felt legitimately threatening becuase of how his boss fights were handled/lack of consequences for losing to him and his personality is just kind of dull IMO.
Without any sense of actual danger that bad things might actually happen because of him or an interesting personality etc I just had nothing to latch onto.
