I loved this movie. Thought it was really well done. The previews pretty much let you know that it will be about this guy's fight with alcohol and the accusations against him after crash landing the plane. I didn't realize going into it that he was going to be an alcoholic, maybe a hard partier who got behind the wheel when he shouldn't have and now he has to live with one mistake for the rest of his life, but I liked that he was spinning out of control the whole movie. The use of the plane crash was a pretty good metaphor for that.
But it would've been better, more realistic, if Denzel had chosen to save his own arse at the end rather than confess his sins. We would've left the theater hating Denzel, but it would've been more true.
