Something a little unrealistic
This was a great movie, and they obviously went to great lengths to ensure that it was completely authentic in almost every detail.
There was just one thing that struck me as wrong.
Surely, a junior member of his office staff would not (on receiving the message from Matrix) tell a special forces general: "You'd better get out here"?
It seemed a very unmilitary way for a junior to address such a senior officer.
Apart from that, spot on.
