Not as bad as you might think. Segal can't act, but that is OK here. Some fun stuff and it keeps the pace up. A good action flick.
Leonard Maltin/Plot synopsis:
DIE HARD at sea, with cook Seagal playing tiger-and-mouse with thugs plotting to steal nuclear arms from aboard a 900-foot Navy battleship. Seagal's best film to date, though his acting inadequacies point up just how much punchier film would be with a better lead; Jones and Busey are better villains than film deserves. Worth it just to see Steve in a chef's cap. Followed by a sequel.
