I watched that yesterday (after reading the David Byrne article last week).
Good documentary (apart from all the "show and tell" cut and paste video and one or two of the soundtrack choices - Schools out for a burned out school! ugh)
Loved the optimism at the end and how a bunch of people living there see it as a really exciting place to live full of possibility.
(it also occurred to me that if anyone was going to film Samuel R. Delanys Dhalgren - Detroit would be the place to film it)
I am watching the Requiem for Detroit documentary linked in the blog entry, it's well done.
