unless you be american or have detail knowledge of that country history and this film be best avoided . initially attract to it through a fascination for time travel movie and i end up disappointed and confused . the use of colour and black and white do not correspond to the period in time a i imagine initially and i end up totally confused a to what time one be in . the premise for the film be interest but the story itself and to me at least and be far from entertain . there also use of bad and crude language which i abhor in film generally and unless there be a very good reason for it . quite frankly and i be not particularly interested in what jfk do or do not do with marilyn monroe . doubtless and those people who be interested in this sort of thing will find some pleasure in the work . i know it be not easy to make time travel film and a certain logic need to be respect and but if in addition the story line be confuse for the spectator and there be no hope of salvation . admittedly if i know more about american politics at the time and few event would have pass me over but a a european and my interest in this particular part of american politics be limit and even have i myself be a u citizen and i would never never have vote for a democrat .
