First of all, let's be honest here.  There can be no denying that this documentary is a great tribute to Gil Scott-Heron's words and music, but it is clearly not for everybody.  Gil Scott-Heron, while having a legion of loyal fans, has never been a mainstream artist.  His first significant national exposure was probably through his appearance as a musical guest on "Saturday Night Live," when Richard Pryor hosted the show during the end of 1975. On that episode, he performed "Johannesburg" (which he also performs in this documentary).  However, Gil Scott-Heron could not get arrested on the show today, which now showcases primarily mainstream artists like Ricky Martin.  This does not in anyway diminish Scott-Heron's talent or influence as an artist -- if anything it boosts it.  This is particularly true in the wake of this documentary's release on homevideo.
