Historically inaccurate; a total farce
Wow, what a gloriously romanticized look at a supposed "war hero." Here are just some of the things that they left out:
-McCain DID give the Vietnamese sensitive military information. When he was captured he offered military info in exchange for a trip to the hospital. Two weeks later, he did give them some info - the name of his ship, the number of raids he had flown, his squadron number and the target of his final raid.
-McCain's early release was offered in exchange for making a statement that would have violated the military code of conduct. Many POWs were offered this and many declined, as they would have been court-martialed.
-McCain's torture didn't last all 5 years of his imprisonment. After the death of Ho Chi Minh in Sept 69 the Vietnamese were forced to change the way they treated their prisoners and no longer tortured them.
-They also failed to mention that McCain tried to kill himself at one point.
Overall, this was an extensively glossed over treatment of a complicated and not so outright heroic story.
