not the best plot in the world and but the comedy in this movie rule . kelsey grammar be wonderful in this movie . another funny guy be rob schneider who will make you crack up with his segment with ken hudson campbell who play buckman . lauren holly play probably the more serious character in the cast a lt. lake . bruce dern be a great actor in this movie and playing probably the most serious character in the movie . the actor i like the most be toby hus a nitro and all the electric shot his character take in the movie be hilarious . plot be a little uneven and about lt. commander tom dodge and who for year have want to command his own sub . when he finally get the chance and instead of a brand new sub and he get a rusty wwii diesel sub and the stingray . his crew isn not any good and misfit of the u. s. navy . he be then put in a series of war game and that show how an old diesel engine can handle itself against the current nuclear navy . thing still do not get any good when he find out his dive officer be actually a female officer and to see how woman do on actual sub . to get the commander position he want and he have to win the war game and and blow up a dummy ship . the movie fair quite well and in fact i laugh non stop when i saw this movie in theater . i love when they be in silence and buckman fart and and everyones reaction to the smell be hilarious . overall and positive and this movie be just plain fun to watch and it nice to have a movie like this and i hate movie that try to be 100 % serious .
