I saw it Saturday night. I went because of the aviation premise and because I find HH to be a pretty darned interesting character. If I had continued to limit my interest to the aviation aspects, I'd have been disappointed (see "knowing suspension of disbelief"). However, I was quickly taken-in by the mental-health aspects, and came away thinking that this was one of the saddest movies I'd ever seen. Nothing like having your brain turn against you, but leave enough cognitive ability to KNOW your brain is turning against you.
I guess I wouldn't call it an "aviation" flick. In short, two general observations: I was surprised at how well I thought LDiC did playing HH, and I always thought Juan was an OK guy. Guess I wasn't paying attention...
