This movie had my total attention till the end.
Most locations for the filming were authentic and I enjoyed seeing it since I grew up in the D.C. area.
Even though this is a true story and the ending is known before one enters the theater, the movie manages to keep the suspense at a high level until the final scene.
I thought the actors did a superb job.
Breach didn't show how Hanssen contacted Russians; it concentrated too much on trivial information that wasn't necessary. Breach isn't as good as Falcon and Snow Man, Family of Spies, Aldrich Ames, and Master Spy. Also, the score isn't suspenseful.
