I'm just saying this as personal opinion, but if you're not from Detroit, there's a pretty good chance you don't care about that commercial. In fact, I'd say the sort of adversarial tone that "we're not NYC, or the windy city" etc would trigger more eye rolls than fist bumps and head nods, especially in light of the nation's perceptions about Detroit and the auto companies here. People get it, we have a chip on our shoulder. Even more so when up against a commercial talking about luxury with the backdrop of a sub-par city and a relatively bland car.
I'd be curious to see how it scored with a national audience. Obviously people in Detroit are going to like it because we're homers that like seeing our own stuff.
