2003

The Lord of the Rings: The Two Towers 8.7
The Pianist 8.5
The Hours 7.6
CHICAGO 7.4
Gangs of New York 7.2

They got it totally wrong here, Chicago's win was and is completely inexplicable. And if that isn't evidence enough for you, just take a look at the list of films nominated in other categories which rate higher.

Nominated in other categories:
Spirited Away 8.5
Hero 8.1
Adaptation 7.9
Y tu mama tambien 7.8
Minority Report 7.7
The Man Without a Past 7.7
Road To Perdition 7.7
Catch Me If You Can 7.6
Far From Heaven 7.6
About A Boy 7.5
Frida 7.5

As you can see there are several films here which are clearly superior to the eventual winner, and frankly several rather average movies, including two examples of what can only be described as minor Spielberg.

It should also be noted that every one of the nominations for best documentary scores higher than Chicago.
