"The Dark Side" was confused and confusing: On the one hand, CIA was demonstrably not there for us about the nature of the Al Qaeda threat, and (most tellingly) about 9/11). On the the other hand, they're just the best and the brightest. Every analyst at CIA (apparently) submitted a "minority report" on Iraq and (specifically) "no WMD", but somehow the intel estimates said "slam dunk". The President (according to "Frontline") gave CIA the lead on Afghanistan and Iraq, but somehow Tenet was so overawed by Cheney and Rumsfeld (who had been "defeated,thwarted and frustrated by him") that he could only say "slam dunk" when the President himself (allegedly) said "George, this 'evidence' looks a mite thin" (which would have been the perfect time to mention the "minority reports" every "analyst" had presumably submittted).
After the show, it occurred to me that what I had just watched, insofar as it essentially "exonerated" the President, Secretary Powell and George Tenet, was an attempt to get one of those gentleman to say something really nasty about the VP and Rummy (in keeping with the current Democrat "accountability for mistakes says Rummy must go" mantra).
An excellent description of the Frontline presentation.
