Michael Moore's latest documentary focuses on his new book and more assorted attacks on corporations which he deems as inferior or greedy. Although it is somewhat interesting, it is nowhere near as important as 1989's "Roger & Me", which was strongly valid in argument. (When GM CEO Roger Smith laid off thousands of workers just for cheap labor in Mexico, it was probably one of the most dispicable things anyone with four limbs has done.)
But the bad timing is nowhere near severe as the hypocrisy. For example, shortly before the messy 2000 Presidential election, Salon magazine surfaced Ralph Nader's 1999 tax returns revealing that he owns a mutual fund with stocks in Walmart, The Gap and an affiliate of Halliburton Oil (all of which came under fierce attack from the Moore/Nader team) This crusade courtesy of the Naderites may have erroneously lead to the wrong guy being in office, and the Moore/Nader team have taken no responsiblity to their actions, or the hypocrisy which surfaced when the Green Party candidate's stocks appeared.
This just goes to show that investigative commentary can lead to contradictions and often diminish credibility in argument.
