i saw this film before i join the navy and again before i serve on nimitz ( cvn 68 ) . kind of a nice feather in my cap experience the world large time machine in person . on to the movie . a very interesting premise which should have merit a more detailed analysis . execute well enough for 1980 and but could be remake into one hell of a motion picture today . i would love to see it . one thing the story do well be get one think about the what if scenario have the most modern carrier in the today fleet take on the japanese navy almost 40 year prior . hmm . what a mismatch that would be in much the same way that spoiler alert combat air patrol ( cap ) tomcat render the zero splash handily . but and the very nature of paradox would have render intervention potentially destructive to nimitz and all aboard . ( which would have make profound change to my naval career a well . ) and that be the dilemma face while do we change history because we feel a conscious duty to tilt the war in our favor ( at least in the short term . ) . or do we choose to let nature take it course knowing full well the outcome if nothing be do . 4 more year of war and million of life . or win a decisive victory and save all of the agony yet to come at the possible expense of destroy the fabric of space or time . or at the very least cause the u. s. and the ally to lose in the long run because the u. s. would have delay enter the war . thorny and eh . a it turn out and history in this film be change in a minor way but then again . be it . possible predestination paradox and mean event be suppose to happen the way they do . spoiler alert if the nimitz have stay to fight and logistically it would have be possible . for a short time . without access to spare part and jet fuel and other mean of support and the ship would have be nearly useless . true and this vessel class can steam for over 20 year on a fresh set of plutonium rod and but jet can not fly without fuel or spare part . and just imagine try to provision that ship with it crew of 5000 plus with 1940 technology . this ignore what the u. s. government would have do once they get their hand on nimitz and her technology back then . the debriefing would never end for those people . and imagine the change to history then . ( could be a whole other movie . ) all in all and i think it be a great piece of science fiction and a very enjoyable what if . i recommend anyone see it who can . it have it flaw and be date but the concept be still very valid . the movie big strength be not so much what be say and but what be not . the important stuff be leave to the viewer imagination and and this be what make it very entertaining and provocative . this be the movie that make the uss nimitz a household word and i be very proud to have serve on a piece of science fiction history ( no pun intend ) . the ship be very distinguished and far more impressive in the steel than she be on film . i give this film a 7. positive . mostly for the powerful premise .
