this be a highly entertaining sleeper about a naval ship that happen to go through a time warp and end up at pearl harbor just hour before the attack in 1941. realistic acting and special effect and air scene really make this movie stand out from other similar movie . i be really surprised that this film be not more popular and because this be a very unique and fascinating concept for a movie and especially back in 1980. i would recommend this movie to anyone who enjoy a good science fiction film . i be also surprised that it have such a low rating and i be expect it to be rat at least a 7. ill give it an positive . well worth view .
