an aircraft carrier and ( in an unconvincingly contrived way ) and go back in time to the day just before the pearl harbour attack and do . er very little really . other than a few people get kill and ( most of who nobody seem overly bother about ) and one man from the future be leave behind and a dog get send forward in time absolutely nothing of any consequence happen here at all . now a film and ( or more usefully ) and a series and where the ship doesn not go home but instead stop the attack and then deal with a crew that have to come to term with living in a past where their irrevocably rewrite history . now that would be worth watch . imagine the issue to deal with . how would the roosevelt government come to term with this new find asset on their doorstep . what issue would it nuclear arsenal have on both end the war and effect the balance of power afterwards . what interaction would 1000 navy serviceman with a knowledge of a possible future have on the world their parent or grandparent be grow up in . altogether a far more interesting premise than the rather pointless one the film finally opt for .
