I could have done without the 'Wall of the missing' otherwise its almost impossible to make a movie about an urban calamity like that and not have those references pop up. There are visual allusions to the Holocaust as well. Have you read the novel? The movie is quite faithful to its spirit. The novel is Holocaustic.
Yes, and references to ET, i.e. the alien playing with the bike. Spielberg has spent waaay too much time being Spielberg. The guy needs a break.
