I only lived in Detroit off and on for about three years back in the 70's. You do hear a lot of negative talk about Detroit around the country. When I first saw the Chrysler Super Bowl ad, I thought it was great and heard a lot of good comments about it.
Now, seeing more Chrysler ads from time to time with short Detroit clips I think it's some of the best, positive, subtle publicity I've seen for the city. I honestly think it's creating kind of an interesting mystique about the city. Much better than that canned crap from the visitor bureaus.
Just thought I'd mention that.
