I think most of this is fair. The part about race and Detroit is rather interesting. I don't think Money's character was meant to be white, more like racially ambiguous. I do think thatthey shouldn't have revealed that bit in the beginning about her being dragged down the street. It also revealed that the other two were already dead. It was unnecessary. And yeah the white girl getting out was too hamfisted. She should have died. That would have been glorious. Or the blind guy should have died. One of them. I also don't understand how he escaped the basement while cuffed? And managed to get a gun, but it is his house and he is paranoid, so I was willing to believe he had other means and awareness of the space.
Definitely a different experience with a packed theatre. And I thought the daughter piece made him more human and less of a one dimensional character. But you're not the first person to say it loses steam. It just never did for me.
It was just his voice. He's this strong, hulking dude who is merciless on intruders, but sounds like a feeble old man. It just sort of ruined the character.
Also, it would've been nice if they spent 5 mins before sort of showing how adept he was as a blind person in his own house.
