That specific ad isn't bad. They, in my opinion, have used the decaying image of Detroit to their advantage, and that kind of thing annoys me. How many photographers have made careers out of capturing the "beautiful" ruins of Detroit? Too many. Each of them sucks the soul out of the city just a little bit more. There's a reason that you're not allowed to photograph prisoners of war--it's dehumanizing to exploit tragedy. I'm not against Detroit. I'm for Detroit, and I want to see it and its people treated with dignity.
Where in Detroit do/did you live?
