As a longtime comic reader for over 4 decades, much of this series, whilst interesting is stuff I already knew but worth covering again and to educate younger and newer comic readers to the history behind our favourite books. This episode in particular stood out because whilst it has been covered in print, I don't recall almost an entire hour of TV where the impact of a tragic event in 9/11 on comics as been covered, I own books like 'Moment Of Silence' & 'Amazing Spider-man #36', it's a part of comics history I felt and lived and it is great to see it all talked about with the emotional level of the time that spawned those books. 'City Of Heroes' obviously is a reference to New York which many of Marvel's superheroes call home, so the happenings & moods of real life have resonated in the pages of these comic books over the decades which has helped integrate these characters as a relevant part of pop culture.
I should point out another reviewer had issue with Van Jones' comments which he erroneously pointed out that Van said 'Afghanistan had nothing to do with 9/11', he did not say this, Van said 'Iraq had nothing to do with 9/11' which is true. The episode is quite factually based and covers general feeling of the times pretty fairly.
Update to respond to the other reviewer: I did watch the episode a 4th time with subtitles on to be fair in my reporting, and Iraq is mentioned 4 times, Afghanistan is mentioned 0 times in the episode. The line disputed takes place at 21min 8secs, copied verbatim "Suddenly, we're going to invade Iraq, that had nothing to do with 9/11". People can check it out for themselves however. Take care.
