amelie
citizen kane
fight club (great book, too)
seven samurai
there are so many great movies its hard to say what the best ever is. many movies, even movies one would consider "bad", are good for different reasons. for instance, "amelie" makes me feel great, "citizen kane" was directed so well and was revolutionary, "fightclub" speaks to me and is a great piece of social commentary, and "seven samurai" is so moving and way ahead of its time.
shawshank redemtion is amazing as well, and as a huge spiderman fan, 15yrs and counting, i thought the movies were fantastic. i can't see why people don't like them, is it because of the romance? thats a huge part of the character and many of the stories over the years.
and i just saw "walk the line" and i highly recommend it
