The story is so compelling that it overwhelms the serious shortcomings in the production. It is not up to Steven Spielberg's expected quality. The acting is stilted in many ways. But more than that, the story is told in what you'd expect in a 1930s movie where the characters are under-developed (McNamara as a wimp, oh please) or over-played, without the subtlety or nuance one might expect and certainly hope for in a first-rate production. Also, it would have been easy to cut a half hour without losing anything except extraneous stuff. The casting is made for the television-binging afficionado, in that the lead spy from the Americans playing Daniel Ellsberg, Saul from Breaking Bad and Better Call Saul for the hot-head reporter, along with others from the West Wing, Mad Men, Breaking Bad, Studio 60 on the Sunset Strip, Glow, Fargo, Gone Girl, The Good Wife, Mozart in the Jungle--and more but you get the idea. All that said, it's well to remember the day the U.S. Supreme Court stood up for the First Amendment, which it might have to once again, with the outcome this next time well in doubt. It also is nice to see some courage by people at risk, which there is a grave shortage of these days.
