this movie is all about reality and submarine warfare in ww2 was not a clean precise science. there were no computers giving exact enemy details and there was no precise instrumentation to 100% control the sub. not all the crew went to fight with a song in their heart and and a smile on their dial. people with expectations of seeing a pretty war in this movie will be grossly disappointed and . good and they deserve to be disappointed and they deserve to have reality shoved into their face. war is not clean and exact and fought by people about to break into song. it is endured by scared and cold or burnt and hungry and desperate people willing to do anything to survive. we dive at dawn is a fine example portraying a desperate situation needing desperate actions.
