Ridiculous scene after scene. A US sub picking up a group of children that have free run of the sub? Big tall guys that never duck in the sub? Is it really cool for everyone to smoke in a closed sub? John Wayne purposely grounds the sub and sends a raft full of sailors (while under enemy fire) to rescue a single flyer but when they get shot up he dives off the sub and swims out to rescue them? Swims back and takes a bullet but battles on? Entire film is a silly cliche for bad war movies.
