I wasn't expecting Two Face to die in this one.
Before 7/18, my money would have been on The Dark Knight being "Two Face Begins," with a villainous setup for a third Batman picture with Harvey surviving. My gut told me that Harvey would go on to a third Batman film as the 'super mob boss,' supplanting the Falcone family and establishing a hyper-militant, draconian order in Gotham headed by Harvey himself. In the process of escalation, this seemed to make sense, and would have given rise to a natural sequel - if Nolan had desired.
Since Harvey didn't survive The Dark Knight, I find myself wondering, like most of you, where a third picture would go. That question aside, another question that's been nagging me is this: Was it the best use of Two Face to kill him in The Dark Knight?
A couple thoughts on that:
No denying it, The Dark Knight's ending was terrific. Harvey's death completely underscored the sense of loss that drove Batman and Jim Gordon to cover-up his deeds, and it's one of my favorite endings since Batman Begins.
However, I assert that Harvey's fall was complete before his death, and his killings represented a complete turn from his path of justice. Therefore, could The Dark Knight have kept its central point without killing-off the character? Granted the film couldn't have ended with Batman directly taking responsibility for Two Face's acts - Two Face would have gone on to disillusion Gotham of that notion. But by the same token, it would not have changed Batman's place in Gotham as its dark knight. That point would have stood, even if Harvey had lived.
My qualm with Harvey's death is that it made The Dark Knight seem audaciously full - I'll stop short of saying too full. The complete arc of Harvey's introduction, through his pursuit of justice, through his fall and ultimately his death seems to strain a 2.5 hour running time. Not that it wasn't great, I just think that there's an air about The Dark Knight that it's trying to do something with a time limit, and that shows up for some critics as being rushed. Specifically, I think Harvey's arc is responsible for that. We have to see him from intro to death in a short period of time.
Instead of taking that route, what if The Dark Knight introduced Dent, showed his White Knight pursuit of justice, and ended with his fall and the rise of Two Face? Would that have totally bankrupted the point of the movie? Would that have left Harvey in place for a powerful sequel dealing with his role as an underworld boss different from the previous Falcone/Maroni mobsters? Does his death rob Nolan of a great character on which to base a subsequent narrative? Does it rob Batman of one of his greatest villains with which to have a more dedicated outing the next time?
