There's saying the same thing twice. There's beating a dead horse. there's criticising Justin Bieber. There's playing World of Warcraft. Then there's playing Final Fantasy 13. Then there's saying that David Cage can't write.
Still, Farenheit (Still a better title than Indigo Prophecy) has a pretty good soundtrack. Not sure if it's original, but Wikipedia says he's a musician, so he might have composed it himself. So that's always a plus. (Among the horrible story, the lackluster choices, the stupid action sequences, and.. voice acting...)
And really, he's not unique. He's just dumb. Would you say an idiot running into the room with a traffic cone on his/her head screaming things in Arabic is unique? Well, it's probably not happened many times, but would you call it unique? No. You'd hit them and tell them to leave.
As for the Maddison Page issue, well, she's a doormat. That's her character. Carla's character is that she is a woman. Maddison's problem, entire personality, role in the story, and gameplay quirk, is that she is a woman. Besides, that woman comes into contact with too many sharp things, so I just got her killed instantly so I wouldn't have to deal with her hammy, annoying voice acting.
