Was It Too Early

The last two nights I've been captivated by The National Geographic Channel's show Behind 9/11. I don't know if anyone else caught the show but how did you feel about the show? It was very interesting to see how things developed but the images of the World Trade Center being hit and then crashing made for a tense last hour and a half of the show. However within all the horror, true stories about some heroes that saved a lot of people from death. So what do you think?
