Not much to say about this one.
The editing was very good, if it wasn't for Gangs of New York, I'd say Chicago would win the Best Editing Oscar.
But otherwise, I didn't think the movie was that great. The dance numbers were actually outside the context of the story, whereas with Moulin Rouge (a vastly superior film), the song and dance numbers were included within the story.
