a a former submariner and this be one of the bad submarine movie i have ever see . first of all and a mutiny aboard any u naval vessel and particularly a nuclear powered trident submarine in unthinkable . these men be the best of the best and be dedicate to their mission . the responsibility they carry be awesome and they take it very seriously all the way from the captain to the most junior crew member . i could never see a crew of any ship split their alliance between the captain and the executive officer . an executive officer who act a the character play by denzel washington do would be relieve of his duty and court martialed and then drum from the navy . it be no surprise the navy refuse to send a technical adviser to help in make this film . lastly and if any member of a submarine crew make the amount of noise make underway on this vessel they would be severely reprimand . submariner learn early in their career to be as quiet a possible to avoid detection . they do not slam door and even speak quietly and wear soft sole shoe when underway . i be amaze at how loud they portray the crew while underway . loud music would never be tolerate . i know portray submarine life in reality would not sell movie ticket and but this be over the top to the point of be ridiculous . i would not recommend this movie to anyone .
