from the plot to the prop and to the horribly tasteless computer generate graphic and right down to the acting and this movie be really flaw . on a positive note and i will give credit to the writer or director or producer of this film who attempt to tell the story of our navy submariner . however and next time and please take some additional time to conduct the proper research on proper wear of navy uniform . in this age of google and many other search engine and this information could have be easily obtain and and the realism truly bring out in your art . instead and the uniform create numerous distraction from the plot . if all else and u. s. navy sailor and like myself who wear the cloth of the nation and when view a portrayal of our duty and deserve to see them portray correctly . anything else and my friend and border heavily on disrespect .
