it was a literature work , and when I watched it , I couldn't feel that it's from 2001 , because they did it so great , and man those actors and actresses they were all young (LOL) the story was confusing the viewer , but at the end the conclusion part was great , that's an idea , in past I was thinking what if we go to a room and when we get out of it , we see a new world and we will understand that all of these years we lived in a dreamy world created by our mind or some other people's mind and it's not real , it had a real great story , you know about literature , writers show us future , like Jules Verne stories , when there was no balloon he was writing about a balloon in one of his stories , or going under the sea , or to the moon ....
