historical accuracy aside,i think this is one great movie.the events take place during the second World War.it focuses on a small group of Americans with a very important mission,one that would eventually turn the tide of the War.virtually all the action takes place at sea,and i gotta say,the intensity in this one nearly wrecked me.there were times i could barely breathe and other times i thought i might explode.if you like nail biting down to the millisecond suspense,you will probably really enjoy this one.there's not a lot of room for character development,but that's a good thing in this case.in fact,i think it may have ruined the movie or at least lessened it's impact.this is one nerve shredding film.Jonathon Mostow directed the movie,and wrote the story and the screenplay.he also directed and wrote the story and screenplay for Breakdown,another great film.anyway,i could go on forever,but for sheer tension and suspense,this is,hands down the best movie of it's type that i have seen,and i've seen some great ones.if this seems like your type of movie,then i recommend you check it out.i also recommend The Hunt For Red October and Crimson Tide
