A good (but not great) submarine flick. Not sure what is missing, but this almost could have been a great film. There are good plot twists, action is exciting, big name actors, but something is still absent. Found it very distracting that the main villian's rank shoulder boards were badly made. Looked like the red star was badly glued on and ready to pop off all the time. Still, if you enjoyed "The Hunt for Red October," then you will have fun with this modern update of the naval classic.
