Revolutionizing film by ripping off 24
Scott Pilgrim vs The World had the most inventive film editing of any film in 2010.
The entire Patel fight is a great showcase of it.

The timing, the text, the effects. It's comic-y yet in live action. The fact that it was nominated by the American Cinema Editors along with Black Swan, Easy A, The Fighter and The Kids Are Alright as the best edited film in 2010 proves this.
Quality is subjective, but in terms of visual aesthetic and editing, Scott Pilgrim really was unparalleled last year.
