A crisis JFK caused by and ended up with Castro in power forever after
Yeah, over-inflating Kenny O'Donnell's role sort of ruined the movie for me. I can't see him pushing JFK around as much as he did in the movie. It was like he was the "real" president. I did like the weaselly portrayal of Robert McNamara and both Kennedy brothers were good.
I really prefer the 70's TV version called The Missiles of October. William Devane made a great JFK, and Ken O'Donnell came off as the butt-boy he probably was.
