Action packed awesome!!!! Great message behind the movie!!

Great movie, lots of action and suspense. Being a Navy Vet, it was very realistic and depicts Navy life board submarines very well. On a sided note when the captain of the boat walks in to a space, "Attention on deck" is callout by the sailors and then the captain responds by saying carry on. In the movie the captain responded without anything being said, but again Great movie.

One of the best movies in a while, gripping!!

Was a great movie. Good to see a new submarine movie.
