…Was the scene with Joker in the alleyway.
The setup was fine. Batman runs into the alley to see his friend dead, and the Joker standing over his body. Batman then proceeds to lose it and come within a few seconds of killing the Joker. The animation was excellent as well, capturing Batman’s fury perfectly.
The first issue with that scene that causes it to lose so much of the impact it had in the comic was Gordon’s characterization. In the comic, Gordon actually grazes Batman with a bullet or two before reminding Bruce of his “role models” and “the beliefs they instilled in [him].” The brilliance of this line is the implication Gordon knows Batman’s identity, and is only willing to use that knowledge to save Batman from doing something he will regret forever.
It also messes up Batman’s reaction. For nearly the entire issue, we get Batman at his most pissed off, throwing aside Harley and Catwoman just to get to the Joker, beating the Joker within an inch of his life… and then in contrast acting so vulnerable and grief-stricken when Gordon convinces him to stop. In the film, Batman seems to revert to his usually stoic demeanor the moment Gordon gets him to lay off Joker.
And finally, it cuts out this masterpiece of a quote, and one of the best moments of Gordon and Batman’s relationship.
BATMAN: How many more lives are going to let him ruin?
GORDON: I don’t care. I won’t let him ruin yours.
Overall, I really enjoyed the hell out of this movie. The changes they made were mostly to serve the story, and there were some downright brilliant twists in some spots. But this particular scene did not get the treatment it deserved.
