I, too, thought the premise - a detailed look at the month from the perspective of newspapers and other media, would provide an interesting slant on the subject.
To a great extent, it did. Particularly from the aspect of American society of the time.
At first, the shoddy editing was just annoying. When there were errors in established historical fact, that did it.
An example of where the two combined: Chapter 14, after a paragraph regarding displaced persons stranded with no way forward and no way back, this sentence - "Somewhere, Bogie and Bacall were stuck too, and time went by." The gratuitous joke didn't fit and should have been edited out, but if it must stay, at least let it be accurate to the film.
An editing example: Chapter 7, on the left side of the page, "One of the first people FDR met with after his phone call from Knox was Charles Fahy, solicitor general of the United States." On the opposing page, "Earlier, he'd met alone with the Solicitor General of the United States, Charley Fahey."
Among the factual mistakes: John Magee was not a "Washington native" and did not fly for the RAF, rather the RCAF. Goering's "Meyer" comment was made in reference to Allied bombers striking Germany, not in reference to the Battle of Britain. The war message from the Japanese Embassy had 14 parts, not 13, as repeatedly noted. There are others that I noticed, an unknown number that I didn't.
After taking a highlighter to several chapters, I just quit before Christmas.
Don't buy it.
