Michael Moore - Bowling for Journalistic Integrity?

I haven't read Michael Moore's Stupid White Men, nor have I seen the movie "Bowling for Columbine" -- although I expect I'll rent the movie (simply because a good number of my friends or co-workers have raved about it ), and will undoubtedly never get around to reading the book (more substantial things to read than one man's tirade against America). At any rate, Michael Moore apparently has a tendency of playing fast and loose with the facts.

Back in April 2002 Ben Fritz's blog "Spinsanity" documented some of Moore's errors in Stupid White Men, the cause of which he believes is "Lazy cribbing from media outlets and the Internet." (Just so you're aware, Spinsanity goes after the lies and distortions of those on the ideological left and right). On November 19, 2002 and Nov. 25, 2002, Fritz exposed additional errors and/or deliberate misrepresentations in Moore's "hard-core analysis" in the movie "Bowling for Columbine", including Moore's altering of a Bush/Quayle campaign advertisement by inserting a caption which did not appear in the original version, the staging of a scene in a bank handing out guns to new customers, and some slick editing/splicing of two separate speeches by Charleton Heston at an NRA convention.

According to Spinsanity on 9/23/03, Moore has apparently admitted the false caption, which he corrected in the DVD release, defending himself in his latest column. However, a quick surf of the web reveals enough critiques on Moore's film that makes me more than a little wary of believing anything "Bowling for Columbine" suggests:

• "Michael Moore and The Awful Truth:" Volume One,
• Volume Two and Volume Three, by Anthony Zoubek, "a series examining ‘Bowling for Columbine’and what it implies of truth in the documentary film genre."
• Bowling for Columbine: Documentary or Fiction?, by David T. Hardy -- focusing on Moore's misrepresentation of Charleton Heston and deceptive use of footage from various NRA rallies.
• BowlingForTruth.Com - scene-by-scene analysis of "Bowling for Columbine."

P.S. I'm not disputing the fact that Michael Moore may have some legitimate concerns about various social issues -- but his attempt to convey those concerns in what appears to be a shoddy "documentary" seems to be counter-productive.
