This non-entity of a movie doesn't deserve a long review, so here are my brief thoughts. You will have seen every single element of this movie done better elsewhere. It is Die Hard and Under Siege on a submarine, yet so much worse than any of the films in either series. It is utterly predictable and totally unmemorable apart from the single worst shootout I have ever seen in a movie. This shootout manages to be completely mesmerising due to the total lack of jeopardy and the catastrophic editing. It is staggeringly poorly done, however, for this hilariously bad sequence I have added an extra star.
