What makes this Dark Knight Opening Scene great for me is the story that the sequence tells the audience. The story of the Introduction of a Strategic Villain.
Scene Arc: From the kick off of the heist to the reveal of our Villain who cleverly gets away with ALL of the money.
Situation: A bank heist where each of the member are assigned to kill one another off after the completion of their special task.

Moving the story forward: A bank is robbed by the Joker, now Batman has to go after him.

2nd Time
Challenging Situation: Robbing a bank.
Intrigue: Which Robber is going to survive and will he be killed off by the Joker?
Interesting Action: The Bank Robbers killing off one another, and a Bank Manager wielding a shotgun.
Intriguing Dialogue: Allowing a line of dialogue: (I know why they call him the Joker.) to lead us into the Next Scene, & the line of dialogue: (Why do they call him the Joker?) AND
Flipping the cliché: (I believe what doesnt kill you only makes you stranger.)
Tone: Dark and playful.
Lures us into the story: The killing off of one another.
Twist at conclusion of the scene: We meet the Joker. He's been on the heist from the start.
