Loved the authenticity and general faithfulness to the technical side of naval warfare. For me, this is a great movie, I love seeing small little details in how the captain commands his vessel, and every crewman doing their job, and quick glances to the CiC trying to keep track of enemy vessels. The movie didn't need to show the crewman following the captain around and repeating every word that Sonar/Radar reports, but it does so and adds a very nice detail that I found to be great, and also helped build the stress and tension everyone was under.
My only complaint is that the movie could have been longer. I could definately have watched a 3 hour version of this that took it slower in the style of Das Boot. Other than that, I recommend this movie for anyone that loves the more technical parts of warfare and especially naval vessels.
