I agree. Yes, he did an outstanding job, kept his cool, and avoided a catastrophe. However, the entire episode, from takeoff to the remarkable landing in the river, was only a few minutes in duration. It's tough to see how they can stretch that into a feature length movie.
Watch the trailer, they pull it off.
It appears from the trailer that the NTSB attempted to smear him by saying he could have made it back to the airport and he was therefore negligent.
