Game: Shadow of the Colossus
What Makes It Bad: Misinforming the protagonist in order to resurrect the spirits was a foul move.
What Makes It Cool: That voice. That horrible, horrible voice. Seriously.

Shadow of the Colossus is confusing, beautiful, and corrupted by evil. Dormin fulfills that role nicely, even though at first it seems that the omnipotent creature is completely on your side. Even more terrifying is the fact that Dormin isn't ever really secretive about his intentions and actually does what was promised. Sure, you get what you wanted, but at what cost?
