Zenos is, much like G'raha Tia, some of the game's worst writing as far as I'm concerned. Both come at the expense of characters with far more depth and nuance. Both have a forced and contrived obsession with the player character and both continue to overstay their welcome in the eyes of many.

Given that Zenos is also one of the few characters deliberately written to have no redeeming qualities whatsoever I also find myself raising an eyebrow whenever people praise or sympathise with him. Especially when that praise involves attributing factors and depth to him that simply isn't there.
