the fact that after 50 year and it be still a highly watchable movie and say a lot about it . it be more intelligent and interesting than almost all recent movie of the same genre you can find and and have a certain endear feeling of innocence to it . i be not a big fan of this type of movie and but i could watch the whole thing without be bore and which make it a good movie to watch with someone who do not necessarily share your taste in film . i like the black and white palette and the excellent casting and the clever heist scene that keep you guess about what trick they will pull next and and the end like everyone else . watch the heist sequence make one realize the power of silence and which be unfortunately so underused in today cinema .
