the only enjoyable thing about watch this movie be make fun of it . the plot make no sense at all . the movie making problem be numerous . the opening scene have lundgren involve in a mission steal what would appear to be a u stealth aircraft and but from whom . some of them wear u uniform and some wear a hodge podge of various other uniform . it be not explain . the submarine set look nothing like a sub include concrete pillar and cinder block wall in some shot . the follow include plot spoiler but since the movie be very predictable they do not spoil much . here be just a few of the problem represent it be not explain how the terrorist get on to the sub in such great number . the virus incapacitates and kill most of the crew within second but the terrorist continue to operate fine for a long time when expose very directly to the virus . dolph lundgren action directly result in the destruction of a u submarine and crew but be portray in the movie a heroic . a u fighter plane change into a swedish fighter and be then shoot down by the terrorist in the sub use a missile design to sink surface ship . the u navy then launch fighter aircraft who launch air to air missile which miraculously turn into torpedo . the many torpedo fail to hit the sub in spite of no one be in the control room to launch counter measure or take any evasive action . the two remain character at the end of the movie have about a zero percent chance of know how to surface a submarine but do not seem worried . i could list many more .
