I agree with everyone that it'd be nice to have a straight-up concert video included like Concert for George ... but I suppose having actually been to the concert last year, it's not as important to me to have that.
That said, I still like the DVD, given that rather than being a concert film, it's supposed to be more of a "documentary" of the whole concert experience ... so the cutaway shots and whatnot add to it some, in my opinion. (though there is a such thing as too much).
Plus, some of the audience reactions are rather amusing to watch. :p
And it's fun trying to pick out which shots were taken in Detroit.
