Query: An empty glass

This film is a sorry excuse for a documentary. 90% of the time all there are segments of random events that Glass is involved in, wether it is a phone call, plugging in his VCR, walking down the street while talking about things unrelated to his music, and other times where nobody is really saying anything. This film seems like the material that ordinarily would have been left on the cutting room floor. I was very much let down by this film, since I am a serious Glass fan. I expected much more than this drivel!! Total joke!
