I finally got around to watching No End in Sight last night.
First of all...Holy fucking shit, Rumsfeld was a retard.
Second...it kind of changes some of my thinking on the war's initial winnability, and how massive failure wasn't inevitable. This was made before "The Surge" (of "is working, my friends" fame) and doesn't make Gates or Patraeus part of the narrative, but definitely leave the impression that the war might have worked had the DoD not been populated so heavily by idiots in March of 2003.
