This was good. Like most documentaries (especially multi-part docs) I felt it was a little slow moving and drawn out, but that pacing also matched the somber tone throughout so perhaps it was intentional.
I learned some things while watching it. I'm sure others were aware that Oswald also shot and killed Dallas cop that day who was trying to apprehend him. If I knew that once, surely I'd forgotten it. I also didn't know that Kennedy was buried on JFK Jrs third birthday That fact makes his iconic salute of the casket all the more painful.
The deceased policemen aside, the Dallas cops don't come off too well in this story. How they ever let Jack Ruby hang around that basement and get so close to Oswald is beyond me. I understand why some people are convinced there was a conspiracy (I don't know nearly enough about it to even venture an opinion) because the only other explanation is complete and utter incompetency).
Whether you lived through that day or not, if you have interest in US history, especially told through eye witnesses, I'd recommend this documentary production by Nat Geo.
