The Leonard Maltin movie guide describes this World War 2 movie as being "sluggish". To some degree I would have to agree. Despite the movie taking place on the ocean battlefield, there often seems to be some sort of spark missing, with an almost casual feeling taking place instead. While I'm not looking for Michael Bay speed and edits, more adrenaline should have been injected. The leisurely pace is not the only thing dated. While some of the Oscar-nominated special effects *are* good, there are a few special effects shots that may provoke giggles from modern day audiences. And the ending wraps things up a little suddenly, and may be unsatisfying to some viewers.
Fortunately, there is more good than negative stuff. Glenn Ford and Ernest Borgnine give solid and believable performances. (And there is fun seeing L.Q. Jones and Dean Jones among the supporting players.) And while the movie may be leisurely at times, it doesn't get to the point of being boring. If you are looking for a submarine warfare movie, you could do worse.
