To a degree yes, but that shouldn't be held against gonzo, it's not gonzo's fault Moore is a lying bag of puss. But definitely putting the documentarian in front of the camera and showing his attempts to get the interview instead of just the interview is gonzo. IMHO the guy that moved gonzo to TV was James Burke with his series War Walks, that move from simply showing the room where Wellington gave final orders before battle to having the host stand in the room discussing what Wellington could view from there was a big change, and for the better as it really removed a lot of the dry dull shell from around documentaries, making them much more approachable and human.
After 'Fear and Loathing on the Campaign Trail' it was impossible to put the halo back on Presidential election campaigns.
