The plot was pants, but the experience of watching he movie unfold was brilliant. Just the cinematography and the music alone was worth spending that time and money on.
If the plot was terrible, the visual aspects didn't impress me at all (it looked way too shiny and polished, some elements were trite - the snowy-white locations, the red desert ones; or taken from previous movies, for example Spielberg's AI). The music was generic but bombastic. The kung-fu fights completely unnecessary and pointless.
