The movie had great effects!  and was not bad at all!  The ending was no surprise! it ended exactly true to the original story and the 1953 film! There were other obvious flaws but the ending was a bit weak!
Why Spielberg felt that he had to let the "Jerk Off" son live is beyond me!  Endings don't always need to be happy!  after all a billion plus people were alread dead at that point!....
