this movie do more to explain and use and and get character out of and time travel paradox then anything i have ever see on the screen . this movie blow me away with how it handle what have seem like a goofy premise when the flick have come out . i have now watch it from begin to end on three occasion and and it continue to blow me away . the casting of the father and son in 1969 and the present day be great and and watch the son unfold with every change in the past be wonderful . why this movie do not even get nominate for a hugo award ( the award give by the world sf convention each year ) amazes me it should have win the award .
