Great cinematic thriller-adventure! Gerrard Butler was outstanding! Gary Oldman never disappoints. Cinematography was so amazing! Cool movie I'd definitely recommend.

This is a good action picture, with a compelling though somewhat predictable storyline. The acting is generally quite good though not award worthy.In several instances you could feel the audience on the edge of their seats. I felt the one aspect that was lacking was the special effects. For example, several shots on the exterior of the sub looked like they were filmed in a local swimming pool.

Good story with twist and turns. Butler did his usual great job!

Action packed and well taken to project American heroism
