The first light cycle segment where Quorra and Anon leap out of Zuse's doomed nightclub and drive down on their light cycles, battling enemies along the way. All the while, "Derezzed" by Daft Punk plays in the background.
For all of its faults, the game was able to have Quorra and CLU realistically modeled after their actors without invoking Uncanny Valley. Especially for the latter, which was a common complaint for the movie's depiction of him. It helps that his facial expressions are a lot more dynamic, which is amazing for an early 7th gen console title.
