I love how true to the theme of the entire film Ledger’s Joker and the motivation behind him were. Because the motivation could never really be quantified, and that’s what makes it so memorable and terrifying.
Whereas Batman Begins’ central thematic obstacle is fear and The Dark Knight Rises deals with pain, this movie is all about chaos - throwing a wrench into the machine and watching it fall to its knees, not because you’re oppressed by the machine, not because you are morally opposed to the machine, but because destroying the machine is a thing that you have the ability to do, so why not do it?
The Joker wouldn’t be nearly as unsettling or effective if he was humanized with a backstory, so he is introduced as an anomaly, a singularity collapse of reason, and he stays that way so you understand just how little you can be sure of about what he’s doing. Because what you’re in the dark about is so much scarier.
Oh my god fucking ignore me I just really like this movie
