For viewers who have personal interests in naval operation, this will not be the movie for you. This movie is full of inaccuracy in portraying submarine operations. For instant, the submarine in the movie has so much space inside that it is comparable to USS Enterprise; None of the seamen (other than the captain) wear their ranks on the work rig; Surface out of nowhere and 'kidnap'two scientists out in the ocean; Fire a torpedo without a guiding wire; Emergency surfacing the ship at 90 degree angle...etc. Perhaps the producers/scriptwriter should have done some research and talk to retired submarine communities before attempting making such movie.
In summary: Awful, just awful
