NTSB not the Bad Guys

Rating: 5/10 (3 March 2017)

Great story. Great guy, a true hero, in fact. Mediocre movie. Why? I give the movie only 5 stars because I question the portrayal of the NTSB as the "bad guys". Ah, but in Hollywood's version of reality there always has to be bad guys. Right?
That is my only criticism of the movie. My wife and I actually enjoyed it, and I cannot think of anyone else who could have played Sully so convincingly. Hanks portrayed accurately the reality of what Sully experienced.
I waited until I read Sully's book before writing my comment. I wanted to know if the NTSB hassled him as much as the movie depicted. There was nothing there. If there was, at least Sully did not write about it.
Does Eastwood not fly anymore? Does anyone involved in this movie not fly? Even if the NTSB did ask hard questions, that is their job. No need to imply that they had bad motives.
