I don't understand how anyone could see this and think that American Sniper is unambiguously endorsing Chris Kyle's view of the world. Like that film, like Jersey Boys, Eastwood here is on the side of a delusional American, but not his delusion. Perhaps contrast to Oliver Stone's Nixon, which attempts to understand its subject by building up pity for him, rather than empathy. Eastwood lets his Hoover indulge his own myths about himself, poking holes in the facade at opportune moments, while still allowing him a genuine humanity. We get Hoover as he saw himself and Hoover as he was and it's left to us to decide what to do with that which is irreconcilable.
