I did not myself go to see the movie but my inlaws have and they said you can actually tell at what point in the movie Kubrick left off and where Spielberg comes in with his buldozer. Basically it gets stupid after that and what could have beemn a master-piece kinda like crushes under it's own weight as Spielberg tried to mix Snow white with ET and serve it in a platter of chopt smurfs.
